This is a site I must recommend to everyone, yes there have been sites like deviantart but over years it has become to much cluttered and too difficult to browse, on the other hand there is flickr which is on spectrum's other end, both very powerful but nothing is browsable, enter vi.sualize.us, a image social book marking, just log in and check out.

I have introduced my favorite images as widget in my blog . This link is for my favorites
