AnalyticBridge is also (just like RecruitingBlogs) a Ning social network, specializing in analytics and offering recruiters an opportunity to meet and talk to passive candidates. AnalyticBridge has about 70 groups, including a few groups for recruiters.
AnalyticBridge also has a "member of the month" award ($250) offered for the best profile, each month. Candidates for April are currently being reviewed, but the competition for the month of May has now just started.
