Here's a really good topic to gather around: Platforms for Communities of Practice. This "Long Live the Platform" online conference is organized by members of CPSquare.
January 14 - February 1, 2008
What's the best platform on which communities of practice can gather? There are a lot of choices and the choices seem to be multiplying. During this three-week conference we will be looking at many different platforms (new and old) through the eyes of their communities. Moodle, SCoPE's platform, will be one of many featured during the conference. Others include Q2learning, Tomoye, Web Crossing, Drupal, Ruby on Rails, Ning, and Facebook. The conference cost is $100 USD but it makes more sense to just join CPSquare.org since the conference is free for members.

As is the tradition at CPSquare, members who help out with the conferences may bring a guest for free. If you'd like to be my guest just send me email (firstname.lastname@example.org) with the subject heading "Long Live the Platform". The first one to respond is in!
