[Air-L] One Million Community Builders Facebook Group

I'm experimenting on ways to pull people from the "private life" dominated Facebook experience into "public life" exchange. Check it out from: http://www.facebook.com/group.php?gid=121232780528 Have others here researched how people actually *use* Facebook groups? Why some groups take off and grow and other serve as virtual lapel pins? My sense is that with limited functionality and no notification/e-mail alert option, they are mostly pseudo-petitions.
