Deane at Gadgetopia recently discovered the Unconference entry on Wikipedia. This is a topic I created on Wikipedia back in November 2005. It caused a bit of a kerfluffle with Dave Winer at the time, who slammed me indirectly for getting the attribution on the term wrong.
Since I created the entry, it has been edited hundreds of times (only a few by me) and is a nice comprehensive, yet concise, article now. This is one of the reasons why I love the Internet and the Web.
