The biggest problem I see is that while I can log in with Facebook there is no easy way to log out without manually revoking access. Other than that I would be interested in seeing how the community progresses since each new member will bring in bounty points, so the people with bounty points to spare will end up being new members and old members who had won bounty points from new members.

If you get a bunch of members it would be really fascinating to watch how the bounty points flow.
