Nancy Baym: "Do all social networks suck at groups?... You’re continuously prodded to join new groups via the listings of groups friends have joined, but there’s no support for making those groups work... It's a grotesque waste of the power of human connection." (via Rob Walker a.k.a. Murketing via Wendy)
Meetup is focused on The Future of Groups, The Future of Groupware, and bringing out the POWER of groups.
