They aren't random, though. A lot of them are very precisely curated.

I didn't say they were random, but jumping between them is essentially just looking for random pictures. Any post on random images is about as themed as those tumblrs cow linked too, but it's more regularly updated and awesome.

Tumblr's always looked like Photoshop Phriday's with topics that don't end. I do like Philosoraptor, however.
