my 500px

I just signed up to 500px after reading about it in techcrunch seems like people are beginning to quit flickr because they've failed to really improve the site and generally be not cool.

Anyway I signed up to give it a try and so far I'm loving it, its introduced me to a lot of talented photographers because they put a lot of effort into promoting people, the features are better and theres a lot more of them (including themes for your portfolio).

anyone else use it?
