Sounds great. You have passion about startups. But please think twice about your idea of social networking. After color.com failure VC don't accept startups about social networks so much. I recommend you to read this article. http://www.fastcompany.com/magazine/160/bill-nguyen-startups
Very interesting read. I understand completely and that is why I was hesitant to call it a social networking app. I feel that is ultimately what it would be categorized as, but it would be much more than that. In addition to that I have a couple of thoughts on how to overcome the chicken-and-egg problem. Hopefully a working demo, and a large enough user base can offset the bias against social networking apps(I use that term loosely).
