A week from today on May 1, hundreds of WordPress users, developers, designers and general enthusiasts will descend upon San Francisco for the 4th annual WordCamp SF. Since that first WordCamp in 2006, back when WordPress was on version 2.0 (Duke), the number of people using WordPress to power their web publishing — from personal blogs to large-scale commercial sites — has grown by millions. It’s no wonder this year’s event is going to be so great

If you’re unfamiliar with WordCamps, here’s the skinny: the San Francisco event is the flagship, put together each year under the direction of WordPress co-founder and lead developer Matt Mullenweg, who traditionally reports on the “State of the Word” and assembles a lineup of speakers that have inspired him over the past year. This year’s lineup includes luminaries such as Richard Stallman, the father of Free Software, best-selling author Scott Berkun, and Salon.com co-founder Scott Rosenberg. As the final speaker list is finalized, the remaining speakers will be added to the WordCamp SF website, but a surprise or two is still possible.

Though the main event is on Saturday, May 1, there are additional days of WordPress goodness in store. Saturday, May 1 will be the main conference with scheduled speakers. There will be keynotes, session tracks for both bloggers/end-users and developers, and lightning talks to provide a broad mix of content, followed by a raging afterparty. Sunday, May 2 will shift location and tone, with a low-key developers’ unconference for the super-code-focused attendees. May 3 and 4 are conference-free, but a WordPress core contributor in-person code sprint will span those two days, bringing together core contributors old and new from around the globe for two days of intense hacking (and let’s face it, 3.0 bug fixes).

If you’re in the Bay Area, or can be, and want to attend WordCamp San Francisco, go get your ticket today!
