WordCamp San Francisco is the official annual conference of the WordPress open source project. This years conference will be in August 12-14, 2011. And, as always will feature Matt Mullenweg's "State of the Word" address as well as a variety of amazing speakers that you'd normally only get to see at expensive industry conferences.
This year the program will be expanded to three days, with programming for publishers, bloggers, and developers. There will also be related activities, like core team summits, workshops for contributors, designers, and local organizers, and various professional and networking events.
WordCamp SF 2010 brought together 700+ WordPress users and developers from around the world. In 2011 we're expanding the programming for publishers, bloggers, and developers.
