I've been a member of the Yahoo! Answers community for quite some time now.
There is a community on there called Religion and Spirituality where there can be some very good questions posted. Of course, this is the Internet, and there are plenty of trolls and ne'er-do-wells out there, but for the most part, it's pretty low key and informative.
These types of communities are good for getting a non-scientific pulse on popular opinion, which is good for perfunctory research.
So, welcome R&Sers!
