So it's not quite where we want to be in terms of design - but the social media blog is now online and I'll be a social contributor. I like the discussion capabilities here for social topics and general social media discussion - http://www.socialmediamagazine.com/social-tags/. And the social media blog will make it easy for people to respond via comments quickly to other social media items highlighted online.

Perhaps the blog will even spur some new social media discussion just like the main social media articles.
