It can sometimes be hard to find the gems among the masses on flickr. But this super cool site ffffl*ckr saves you a bit of time, whats really cool is its not like weheartit, showing what other people like and then you cant find the source.
You can use it to find the photography you like using the simple idea that people whose work you like, probably like stuff you'll like. By clicking on images you like, it shows you what that photographer likes. And it links right back to their flickr page. Its a pretty cool tool for making great flickr discoveries.
