Automattic

WordPress.com

The open source WordPress package was famous for its 5-minute install, but as simple as we could make it the barriers to getting a WordPress blog were still fairly high and technical. Enter WordPress.com, a version of WordPress that is hosted and completely maintained. Thousands of people every day are creating blogs on the WordPress.com service, which has just begun to explore its capabilities.

Akismet

If you’ve been blogging for any amount of time, you’ve probably experienced how spammers can suck the joy out of managing your blog, and some people spend more time deleting junk than they actually do creating content. Akismet is our way to address this. It’s an adaptive, self-learning spam protection service that has proven highly effective, blocking millions of spams a day with a 0.001% miss rate.

WordPress.org

WordPress is an open source blogging tool used by everyone from Rosie O’Donnell to the New York Times, and WordPress.org is its community home. Development is led by Automattic troublemakers Matt Mullenweg and Ryan Boren, along with community members Mark Jaquith and dozens of others. WordPress has grown from a tiny project to what is by many accounts the most popular blogging software in the world.

bbPress

Forum software is notorious for being bloated and insecure, and bbPress is pretty much everything most modern forum software is not. Sharing the same philosophical roots with WordPress, the most prominent installation of bbPress is the WP support forums themselves, which have hundreds of thousands of posts yet still are as speedy as can be. All the features you need – like tags, AJAX posting, categorization, modular user system – and nothing you don’t.

IntenseDebate

IntenseDebate is a comment system that enhances and encourages discussion on your blog or website, with comment threading, reply-by-email, and easy importing/exporting of all your comments.

PollDaddy

The premier way to create polls and surveys on the web, Ireland-based PollDaddy joined the Automattic family through acquisition in October of 2008. Using their WordPress.org plugin or the tight WordPress.com integration, WP bloggers can easily integrate polls onto their sites. PollDaddy is also platform-agnostic and can be used an a number of other platforms.

Gravatar

A gravatar (globally recognized avatar) is quite simply an image that follows you from weblog to weblog appearing beside your name when you comment on gravatar enabled sites. Avatars help identify your posts on web forums, so why not on weblogs?

BuddyPress

BuddyPress will extend WordPress MU and bring social networking features to a new or existing installation.

BuddyPress is essentially a set of WordPress MU specific plugins. Each plugin component adds a distinct feature to BuddyPress and only handles functionality for that specific component (for example, private messaging). BuddyPress also has a core plugin that all other plugins require, it contains shared functions and performs the basic modifications to the WordPress MU interface.

WordPress for iPhone

The first Open Source blogging app for iPhone and iPod touch lets you add and edit posts, pages, comments, and photos to any self-hosted WordPress or WordPress.com blog.

WordCamp San Francisco

One of many WordCamp events around the world, WordCamp SF is a conference organized by the creators of WordPress for our users and developers. It exists to get WordPress users together, learn from each other, figure out the future of publishing the web, and have a good time.
