Back in July of 2007, Andy Peatling posted on his blog about creating a social network called ChickSpeak on top of WordPressMU, the multi-user version of the popular open source blog platform .

BuddyPress 1.0, the result of that effort, was released on April 30th of this year, and is an option that should be seriously considered anywhere a new content-centered community is being built.
