BlogOrlando: September 28-29, 2007
EDIT: I jumped the gun. If you read Josh's post, you'll know this is a "penciled in" date.
Chances are if you participate in Social Media (especially in Orlando), you have heard of Josh Hallet. Or read a blog he consulted for, designed, even influenced in some way. Last year Josh put together a fantastic UnConference called BlogOrlando. Rollins College was a great space for this event, with two rooms and tons of useful sessions. This year will only be bigger and better from what I understand.
