This isn't so much a new business as a new side project of mine. I've noticed a lot of people here and on other blogs and news sites saying how much they would like a place to find business partners. So in my spare time I put together http://www.FounderLink.com to fill this space. I've tried not to make just another social networking site and I am trying to keep the features as few and focused as possible while still being useful for the core functionality(Meeting potential business partners).
Any feedback or suggestions would be greatly appreciated.

like yours, they have various strengths; but a consistent weakness is that there's no inherrent reason for anyone to come back unlike say yc news or meetup.com
