BloggerCon
BloggerCon was a user-focused conference for the blogger community that ran between 2003 and 2006. BloggerCon I (October 2003) and II (April 2004), were organized by Dave Winer and friends at Harvard Law School's Berkman Center for the Internet and Society in Cambridge, Mass. Bloggercon III took place in San Francisco on June 2006. According to the Online Journalism Review, "BloggerCon has lots of cooks, but the chief chef is technologist Dave Winer, co-founder of RSS and the patient zero of blogging. BloggerCon exists because Winer wants it to happen."
