Today at the TechStars demo day, Automattic, the company behind WordPress, announced that it has acquired enhanced commenting system IntenseDebate for an undisclosed amount.

WordPress has long been in need of an upgraded commenting system, which has led to a number of replacement and augmented systems in the last year, including Disqus and JS-KIT. WordPress CEO Toni Schneider says that better commenting has been on the blogging platform’s roadmap for some time, and that IntenseDebate’s team and technology made the company a good target for acquisition.

WordPress 2.7 will include some of IntenseDebate’s features by default, including threaded commenting. The service will also introduce a plugin that tightly integrates the rest of IntenseDebate’s other features, like aggregated commenting across multiple blogs.

In a blog post announcing the deal, IntenseDebate says that it will now be re-entering private beta, though the service’s current users will still be able to use it. IntenseDebate will stay a separate service that will be tightly integrated in WordPress, but will also be available for other platforms (Akismet’s spam filtering has been used in a similar manner).

IntenseDebate originally launched to the public last October, sporting features including OpenID support, user profiles, and the ability to track a user’s comments across multiple blogs. Since launch the site has seen impressive growth, reporting at least a 25% increase in users each month.

Mollom is a new blog spam prevention tool that’s shaping up to be serious competition to Automattic’s Akismet, the current market leader.

Belgium based Mollom was founded earlier this year by Dries Buytaert, the founder and project lead of the Drupal project and Benjamin Schrauwen, a Post-Doc researcher at Ghent University and Machine Learning expert. Mollom automatically blocks comment form spam, contact form spam and fake user accounts using a filtering technique based on the combination of content analysis and CAPTCHA challenges.

When new content is analyzed by Mollom’s intelligent text-analysis filter, and Mollom is unsure whether it is ham or spam, it asks the user to answer a CAPTCHA challenge. This challenge-response procedure doesn’t block human users. If an unwanted message still makes it onto a website, users can help fight back by reporting to Mollom. The service learns from its mistakes.

According to statistics from Mollom (they publish a full scorecard here), the service is 99.94% accurate, making 6 mistakes per 10,000 comments, but one key to the service is its ability to learn as it goes along, so the team is aiming to improve those figures over time.

The business model will be similar to Akismet (they’re currently in beta testing only); the basic Mollom service will be free with commercial/ high-traffic websites paying but getting more advanced features, improved reliability and performance. They also plans to offer dedicated, managed Mollom servers for high-end users. Current Mollom users include Sony BMG, Adobe and FastCompany.

Buytaert told me that although offering the same features as the competition, Mollom’s goal goes further than spam-blocking alone.

We want to increase the overall quality of your site’s content. For example, Mollom’s CAPTCHA service already helps block fake user accounts, and we are experimenting with various automated content-quality assessments, including blocking obscene, violent and profane content.

The service is already getting a lot of positive buzz in the Drupal community and the statistics are impressive. They don’t currently have a WordPress version, but they did ask that I mention they’re looking for a WordPress developer to write one, contact details here if you’re interested.

WordPress 2.5 has been released with a major overhaul to the interface and a range of new features.

The biggest change is in the appearance of the administration backend, which is described as being a “Cleaner, faster, less cluttered dashboard.” The WordPress dashboard is now widget friendly, and users can include items such as stats, offering similar functionality to MovableType.

Other new features include multi-file uploading, one-click plugin upgrades, built-in galleries, salted passwords and cookie encryption, media library, code friendly WYSIWYG, concurrent post editing protection, full-screen writing, and improved search.

Automattic founder Matt Mullenweg has escalated the war of words against competitor SixApart with a new post that further attacks SixApart following a Twitter exchange Tuesday.

Some highlights from the post:

Could you build Typepad or Vox with Movable Type? Probably not, especially since people with more than a few blogs or posts say it grinds to a halt, as Metblogs found before they switched to WordPress….

Automattic (and other people) can provide full support for GPL software, which is the single license everything we support is under. Movable Type has 8 different licenses and the “open source” one doesn’t allow any support….

Movable Type, which is Six Apart’s only Open Source product line now that they’ve dumped Livejournal, doesn’t even have a public bug tracker, even though they announced it going OS over 9 months ago!…

Movable Type once led the market, it had over 90% marketshare in the self-hosted market. Now they call “pages” and “dynamic publishing”, features WordPress has had for 4+ years, innovation and you still can’t do basic things like click “next posts” at the bottom of home page…

For the record, I’m glad they’ve taken the license of MT in a positive direction that prevents them from betraying their customers like they did with MT3, but they have a long way to go before the project could be considered a community.

Certainly SixApart’s history in relation to open source and caring about their community isn’t great (and I won’t be one to defend it). However Mullenweg’s comments are interesting given that Automattic’s biggest money earner Akismet is not open source (the service, not the plugin) and benefits from the the failure of WordPress to combat comment spam natively. Couple that with Automattic controlling WordPress as it was its own; some may suggest this a clear conflict of interest that disqualifies Mullenweg from taking the high moral ground. People in glass houses.

Can WordPress become the basis of a social network? Automattic founder and WordPress creator Matt Mullenweg hinted today on his blog that WordPress might go in a more social direction. He announced a new hire, Andy Peatling, the developer behind BuddyPress, a social network built on top of WordPress. BuddyPress will now become an official WordPress project.

Peatling describes an earlier version of BuddyPress, ChickSpeak (a social network for college women). He built ChickSpeak (and BuddyPress) on top of a multi-user version of WordPress. He moved all the blog posts off to the side and made most of the real estate a profile page with messaging functionality. Finally, he took advantage of all the open-source plugins available for WordPress:

Wordpress also has an excellent plugin API, as well as a whole host of quality pre-built plugins ready to download and activate. The key here is that I didn’t have to hack the core - I could just achieve the additional functionality needed by building dedicated plugins.

Plugins were built and used for private messaging, advanced profile management, online polls, photo management, multi-blog search and user credential management.

It is easy to dismiss this as completely unnecessary given the abundance of social networks already out there, as well as application development platforms like OpenSocial. But an open-source social network does present some intriguing possibilities. New apps and features could be added simply by creating new plugins. And there would be no lock-in to any proprietary code or development environment. Mullenweg writes:

Someday, perhaps, the world will have a truly Free and Open Source alternative to the walled gardens and open-only-in-API platforms that currently dominate our social landscape.

I asked Mullenweg if the world really needs another social network. His response:

The world doesn’t need another social network, it needs a thousand networks that let you own your data and interconnect using open standards. We invest countless hours giving our data to networks like MySpace, essentially sharecropping on their land for the privilege of being able to connect to our friends. It’s our friends, our time, our connections, our data — it should be our software.

I think only an Open Source solution can do that.

Automattic already hosts nearly 2.6 million blogs on Wordpress.com that generate more than 100,000 posts a day. That is a vibrant and big community. Could that be used to seed a social network? Even if BuddyPress remains a completely separate project, it will be interesting to see if it can out-innovate Facebook or MySpace or Bebo as a social networking platform. Does anyone think it has a chance?

Update: Strangely the GNU Public Licensed BuddyPress has had its page taken down by Automattic and replaced with default “coming soon” message with links to the code removed (cache of the original page here). Same with the project page on Google Code, the main page having only just been pulled as the original page is still available to be viewed via Google cache. A subsidiary page with access to the plugin hasn’t been deleted by Automattic yet and is available here. Update 2: The code is back up now. It was taken down temporarily in anticipation of a move to a new URL buddypress.org (not live yet).
