Off the top of my head, Pinterest looks pretty interesting (no pun intended). I heard about it from my Mom a week ago, and then was told about it from my girlfriend, two different podcasts I listen to and a HN post. Probably wouldn't give them the whole 100k, but it's definitely a startup I'm keeping my eye on.
