Hey there thanks for your comment. I am the founder. So I think we've all learned that socializing on the internet is acceptable (ie meeting people on online dating sites, or on message boards, etc.) and what we're trying to do is bring those sorts of interactions to the mobile device. While I admit it's a bit weird to think about now, seeing how the product worked at YC Demo Day was really interesting - we had 200 people in a room and it's hard to talk to all of them at once but the "backchannel" provided an interesting additional medium to interact with people.
