Adobe just announced a bunch of upgrades to Acrobat.com, its suite of web collaboration applications. The most important: It’s releasing an application for the iPhone and BlackBerry.

Mobile support has been a big missing piece for Acrobat.com, since a big selling point of applications like Adobe’s (as well as Google Docs and the upcoming web versions of Microsoft Office) is the ability to access your documents anywhere. Now Acrobat.com users can not only read and share files from their phones, but also upload documents and send faxes.

Acrobat.com started out as a free service, but in June it launched premium versions, where users pay for web meetings and the ability to create PDF documents. The mobile app follows that model. Free users can send two faxes and upload up to five documents from their phone each month, but if you want to do more, you’ll have to upgrade to a pay version.

The other major improvement is the creation of a central environment to view all your files in Acrobat.com, rather than having to view all your documents in Buzzword, all your spreadsheets in Tables, and all your presentations in, uh, Presentations. This may be what Product Manager Erik Larson was referring to when I asked him in June about future improvements, and he said, “I don’t necessarily think presentations, spreadsheets, documents are these three separate things, even though I know that’s the way the world thinks right now.”

The new version of Acrobat.com will launch at 3am Pacific on Saturday, Nov. 21. Larson told me in June that the site has 5 million registered users. (I’ve asked for more recent numbers and will update if I receive them.)

You would think that, almost exactly 4 years after opening up to the public, WordPress.com would have a way for people to subscribe to blogs by e-mail, right? You’d be wrong, at least until today.

While there has always been the possibility to subscribe to blogs by e-mail using FeedBurner or other RSS facilitators, WordPress.com’s parent company Automattic has now added an email subscription feature to the popular free blogging service.

To enable this, simply install the Blog Subscription widget on your WordPress.com blog and you’ll enable anyone to get updates from your blog in their e-mail inboxes, whether they’re WordPress.com users or not, on a per post basis, daily or weekly. Evidently, all subscriptions require confirmation by the address owner and can be canceled at any time.

E-mailed blog posts will come in as HTML, although users can opt to receive them in plain text too should they still be using a mail client sans HTML reading capabilities (seriously, does anyone still use those?).

I’m still wrapping my head around the fact that Automattic has only added its very own e-mail subscription feature now, on the verge of entering the year 2010. E-mail is such a huge deal still, and shouldn’t be treated as an afterthought even by ‘new media’ companies like them.

Good thing they ask us to stay tuned, because they have a ‘lot more plans for email’. What, like the ability to send in blog posts for publication by e-mail like Posterous and Tumblr have been doing for quite a while? Update: as Automattic’s Ranaan points out in comments, that was already possible, my bad. Looking forward to their future plans with e-mail.

Yesterday at the Web 2.0 Summit, Founder’s Fund managing partner Sean Parker gave a provocative presentation entitled “The New Era Of The Network Service.” In it, he argues that so-called “network services” like Facebook (which he helped start) and Twitter will soon dominate the web, rather than “information services” like Google and Yahoo.

It’s a very interesting idea, to say the least, and obviously you’re interested in it, as about 200 of you commented on it yesterday. So we’ve obtained Parker’s full slide deck from his presentation. Find the full presentation embedded below, definitely worth the read.

When Wolfram Research released its iPhone app for Wolfram Alpha earlier this week, most of the attention quickly shifted away from the features of the app itself and towards the high price of the app. At $49.99, Wolfram Alpha is far more expensive than most apps in the App Store today, where only a small number of highly specialized apps sell for more than $9.99. Today, we got a chance to discuss Wolfram’s pricing strategy with Schoeller Porter, the product manager for Wolfram Alpha’s iPhone app.

Sponsor

Early Reactions

On Twitter and in the tech blogosphere, the reactions to the app’s price were anything but subtle. We called it “too expensive” ourselves, though others had stronger words for it. MIT’s Technology Review called it a “a pricey online calculator for geeks” – a product that’s more like the expensive but immensely powerful Mathematica than Stephen Wolfram’s original idea for Alpha (”Wolfram|Alpha aims to bring expert-level knowledge and capabilities to the broadest possible range of people”).

It is worth noting that the Wolfram Alpha app quickly appeared in the list of top 100 grossing apps in the iTunes App Store (iTunes link) and has been hovering at the lower end of the top 50 ever since. That doesn’t make it a breakout hit, but some people are clearly buying the app, even though only a small number of users have left reviews.

A Premium Price for a Premium Experience

There can be little doubt that the Wolfram Alpha team was expecting some backlash. As Porter told us today, the Wolfram Alpha team decided to price the app with the cost of a hardware graphing calculator in mind. At $50, the app costs roughly half of what a hardware calculator would cost. As Porter also stressed, the app offers a far superior range of features thanks to its connection to Wolfram’s server farm. The company thinks this price is justified because of the superior experience of using the app over the mobile website.

After using the app for a few days, we definitely have to agree there. The dual-keyboard solution makes entering queries in the app much easier than using the mobile site and accessing Wolfram Alpha from the app is also much faster then using the mobile site.

Porter noted that Wolfram is trying to set itself off from the mass of $0.99 apps that only get used once and are quickly forgotten. Instead, the company hopes that the app will become a regular companion for its users, whether they are using it for help with their homework in school or college, or in their professional life.

At the end of the day, this is an app for specialists. While Schoeller Porter worded this more carefully in our interview today, the basic fact is that Wolfram is charging a premium price for a premium experience. Users who don’t need the app can continue to use the website, while those who are willing and able to spend $50 on the app will get a superior experience. For the time being, Wolfram doesn’t expect to bring the price of the app down and so far, according to Porter, the team has been happy and excited about how the app has been performing in the marketplace.

The Price of iPhone Apps

This also leads into a broader discussion about the current pricing in the iPhone App Store, where even the most complex apps and games have to sell for under $10 to reach a wide audience. At the end of our discussion, Porter noted that the Wolfram app may lead to some changes here, though we have to wonder if anything is likely to change the current drift towards lower prices in the App Store.

It is also worth pointing out, though, that a lower price point opens up the market for an app to a far wider audience – often to the point where the lower price brings in exponentially more users and more than offsets any potential losses from the lower price.

What Do You Think?

Is Wolfram’s price point for the iPhone app a bold move? Hubris? Or would you be happy to pay $50 for the superior experience and ergonomics of the app?

The new design is a compromise between the ‘old’ News Feed, which used algorithms to present stories Facebook thought you’d find interesting, and the feed Facebook rolled out back in March that consisted of a Twitter-like stream of recent updates. Since this year’s redesign Facebook has used the ‘Highlights’ section at the right hand side of the screen to present items you may have missed, but this was never an ideal solution: for one, you couldn’t see your friends’ comments on these posts, and the small space afforded to Highlights made it easy to pass over.

Today’s change will make the Highlights section redundant, so it will be removed (everything below it will also be shifted higher on the page, which means the ‘Birthdays’ and ‘Events’ sections will no longer be buried). Facebook’s post also notes that the News Feed will include more events, including when your friends become fans of Pages, add friends, or RSVP to an event.

The change has been a long time coming — reports about the merging of Highlights back into the feed emerged as far back as June.

The last thing the world needs is another video site, right? Well, that’s not stopping Aaron Crayford, who convinced a bunch of his supercomputer engineer buddies to put together Rippol, a video discovery site that blends hardcore machine learning with social streams. Rippol (not to be confused with rrripple, the media sharing site) is coming out of stealth today into private beta. Be one of the first 1,000 people to try it by signing up here. (If you don’t get an invite, the site will be launching publicly in a month at our next Realtime Crunchup).

Rippol is still in raw form (the UI needs more polish, not all the buttons work the way they should), but it is experimenting with some powerful ideas in online video. You can sign in with Facebook Connect, or create your own account (it will also support Twitter and Gmail sign-ins soon). Once you have friends on the system, it lets you discover new videos through your friends. The homepage is an activity stream of the videos you and your friends have watched, favorited, rated, and reviewed. And a global stream in the left column shows what the broader Rippol community is watching. Links to any video can also be shared on Facebook or Tweeted out.

You can click on any video mentioned in the stream to watch it, and chat with friends via Facebook Chat, which pops up from the bottom left of the browser window. Displaying videos as a realtime stream of information is a discovery mechanism that we are beginning to see in cutting-edge video sites like Magma (our review). And I suspect it will become adopted more broadly.

However, Rippol doesn’t rely solely on your friends’ activities to help you find interesting videos. The site is also a standalone video discovery engine in its own right. You can watch about 500,000 videos right now in the Rippol player, which can be detached like a chat box and moved around in front of the screen, while you search for more videos, check out your stream or chat with friends.

Rippol ingests videos from other sites like Hulu and YouTube and then it runs them through its “Butterfly Network” (see diagram at right, click for larger image). Here is where the machine learning comes in. The Butterfly Network looks at all of your video-related activities in the site, those of your friends, and those of people in your demographic. All of the videos on the site have particularly good metadata (titles, genres, actors, descriptions), which lets Rippol take advantage of data-mining techniques to recommend videos for you. It creates a genre cloud for different categories of videos (TV Shows, Movies, Sports, News),and then generates a list of videos for each genre tag you click on.

Depending on what genre of videos you are looking for, Rippol’s realtime ranking servers shows you videos associated with ones you’ve watched or liked in the past, your friends have watched or liked, and people in your demographic have watched or liked. If you click on comedies and martial arts videos, those will rank higher for you in the future.

Since Rippol has all the realtime stream data as well, the video results are skewed towards what people are watching right now. Your own actions impact the rankings the most, followed by those of your friends, followed by those of people in your age and gender group. And if you are a 45-year-old male who tends to watch videos more like a 25-year-old male, it adjusts the demo it associates with your actual watching habits.

The system is supposed to get smarter the more you use it, and the more your friends use it. So it’s hard to evaluate how effective it will be right now with only a handful of users, but it is a promising approach. Soon users will be able to suggest videos to add to the site. (Crayford says he’s come up with a novel way to filter out inappropriate videos from the broader community by taking into account what is acceptable to different social groups).

Crayford’s last company, Vusion, specialized in high-definition video streaming over the Web. It’s patents, intellectual property, and other assets were acquired by the Clarendon Foundation in June, 2009. Craydon learned from that experience that advanced technology can only take you so far, and this time around he is trying to create a complete consumer experience rather than just an enabling technology. Rippol is completely bootstrapped so far.

The beta launch of Google Wave has once again put the spotlight on the shortcomings of email. Wave tries to be everything for everybody, but others, like the recently launched Nurphy, have opted for a more focused approach. Nurphy, founded by Paul Horsfall and Neil Cauldwell, wants to be a replacement for email conversations with multiple recipients. The result is an interesting mix between email, Twitter, Yammer and IM that is aimed at both business and casual users.

Sponsor

Conversations Instead of Email

To initiate a conversation, you first have to sign up to the service or sign in with your Twitter credentials, which doesn’t take more than a minute. On the website itself, Nurphy looks a bit like a cross between Twitter and an email client. After you have signed up, you can start a conversation with anybody who is on the service already or by email. Recipients who don’t want to sign up for Nurphy can continue to reply to messages by email.

Conversations on Nurphy are shown in a Twitter-like timeline in reverse chronological order. Conversations can be public, private or by invitation only (though still visible to the public). Public threats – like Nurphy’s own customer service site – look a bit like forums and Nurphy recommends that you post links to these public conversations on your social networking profiles so that you can have a ‘real’ conversation with your friends. Without threaded conversations, however, it can be hard keep track of conversations. Instead of using sub-threads like Yammer, Nurphy borrowed Twitter’s @reply structure.

It is clear that Nurphy’s designers paid a lot of attention to detail. If you ever registered for a Gravatar in the past, for example, it will automatically choose this picture as your profile image in Nurphy. The service also offers a nifty mobile website, which looks especially good on the iPhone.

Needs some Fine-Tuning

The service, however, also still needs a bit of fine-tuning. You can’t edit messages once they have been posted – the only option is to delete the whole message. It can also take a few minutes before an emailed message actually appears in a conversation. There are also a few small design flaws that take a user out of the experience. When you add a message, the whole page reloads, for example, even though the system seems perfectly capable of adding incoming messages to the conversation without a reset.

It almost seems like Nurphy is trying to keep things too simple in its current iteration. While we understand that the company is trying to make it as easy as possible for new users to get started, it would be nice if you could set up a private Yammer-like network for your friends or colleagues, for example.

Microsoft announced this week that it has made a deal to include public updates from Facebook in its search engine Bing. Some Facebook users expressed concern that their private activities might be exposed to search. The real story is a little more complex. To put it simply: Facebook is not ever going to knowingly expose private activities on the site to public search. We can say that with as much assurance as we can say almost anything about the internet.

None the less, Facebook has a clear agenda to convince you the user to willingly expose more information publicy by changing your privacy settings. Multiple Facebook execs have told us so when we asked point blank.

Facebook believes that sharing is good for the world. It was founded on making sharing private and secure between friends – so you’d share more – but it hopes in time to make hundreds of millions of people more comfortable sharing publicly.

As is, searching public activity is good for search users (though many are skeptical), it’s good for search engines and it’s good for the social networks serving up the data.

But is it good for social network users that don’t want their messages showing up in search results? That’s the wrong question to ask because that’s not going to happen.

Your Facebook profile is private by default. Your messages and media can’t be seen by anyone but your friends. Some small number of users have chosen to change those settings, some even making everything they do on Facebook publicly visible to the whole world. Clearly some users would find programatic analysis of their activities anonymized and made available in builk to be a violation of privacy – but many more would not and are all ready wide-open.

That group is probably made up mostly of self-promoters, marketers, overcompensating lonely people and other exhibitionists. (My profile is public, I fall under the self-promoter category, unfortunately.)

Facebook would appreciate it if you would put yourself in this category, too. The company believes that sharing leads to understanding between people, empathy and progress towards world peace. Sharing also provides nice opportunities to advertise.

Facebook wants to display lots of your information publicly, but it won’t shoot itself in the foot by breaking its promise to respect your privacy settings – whatever they may be. Is it strange that Facebook, now more populous than all but three nations in the world, has such a clear agenda to change the world’s culture? It is certainly something to be aware of. But Facebook is not going to make your private messages public.

This week brought news that Google and Microsoft are now incorporating Twitter into search results, solidifying the importance of incorporating social media content into search results. And startups like OneRiot have also recognized the value of tapping into the Twitter stream for search. Startup Kikin is doing the same with its newly launched plug-in.

Once installed, Kikin will integrate content from social networks (like Facebook and Twitter) and other social sites (like Amazon, eBay and YouTube) alongside results from search engines (like Google, Bing and Yahoo!). So if you search for chocolate labs on Google, Kikin will provide a pane of YouTube videos of chocolate labs and a Twitter stream of mentions of chocolate labs.

You can filter Twitter search results to just the Tweets from those users you are following. The pane also acts as a Twitter client where you can retweet Tweets and more. And the search results will tap into your Facebook account via Facebook Connect and search your news stream. Kikin lets you alter your settings so you can only see results from Twitter or YouTube.

While Google, Bing and other search engine embrace social media content in their search results, I’m a fan of Kikin’s plug-in because it lets you moderate what content you want to see and which content isn’t useful to you. You may not be interested in results from eBay for your searched, which you can disable (of course, it will still show up in your Google results). And I like that Kikin accesses your Facebook stream and YouTube videos. And if you tire of Kikin’s results, you can easily minimize the pane.
