YC latest Batch. Which is your favorite startup?

I think we can all agree that this YC batch is quite different from the previous one. We are presented with more fully developed applications with business models. What are your favorite products/services? Mine: PopCuts because it has the potential to disturb the music industry. Polleverywhere: Because it is well needed and super simple. Think how many people voted for American Idol by SMS and you can see how Polleverywhere has a potential to take it mainstream. I see it a the PollDaddy or SMS. JObAlchemist because recruiting is a "frea.." pain point and anything that makes it easier will generate cash. I would not be surprise if this one gets acquired super fast. PicWing. Because my people love to capture the best moments and hang them on the wall.
