WordCamps are attended by people ranging from blogging newbies to professional WordPress developers and consultants, and usually combine scheduled programming with unconference sessions and other activities. For more information on common WordCamp elements, read about what to expect at a WordCamp.
The first WordCamp was organized in San Francisco by Matt Mullenweg in 2006. Since then, local communities around the world have organized over a hundred WordCamps, and we anticipate that number will pass a thousand within the next couple of years.
