Thanks, although somehow I think that unsubscribed me from updates, so from the lack of emails I assumed people weren't interested and I haven't been checking back.

Sorry about the silence, I'll catch up with the discussion soon! I've got a big hackathon this weekend (TechCrunch Disrupt http://techcrunch.com/events/disrupt-sf-hackathon-2012/) that's going to take all of my energy until Monday. But I am really excited about all these suggestions. Thank you, and keep them coming :-)
