not bad... just 2 suggestions:

1. why isn't there a "stumble" button? or maybe there is and I didn't notice? From what I understand to only way to see the next image is refreshing the page

2. I would love to have a "filter this person" so the app will know not to show me photos from this person, because he doesn't interest me.

other than that - cool!

EDIT:

oh, and another idea. It takes quite a while to fetch the data. So if you implement the "stumble" button, it would be nice if you start fetching the data before I even click. immediately when the last data has finished fetching.
