Great project! I remember seeing the possibilities of something along these lines, when I browsed the recipes of ifttt that crawled your social feeds for photos by yourself and others and saved them in your Dropbox folder. If this folder were shareable, it would create a different social network all by itself! And better yet, I wouldn't have to sign up for silly social networks and Facebook in order to get access to that data.

I don't know if this is disruptive, but I hope this will help break the data lock-ins networks like Facebook and Twitter photo services are using to retain and attract users. (And what happens if one of the sites go belly-up with all your data?)

If I could make one suggestions, the site as it currently is looks like one for a generic software download. You should, eventually, try to make it look more friendly and inviting as if to say that this is a social ecosystem of sorts.

Best of luck! If you're in SF or NYC, you probably won't need it with all the people who'll throw themselves at you over a great idea like this. :)
