WTF, Evolution? is the most enjoyable Tumblr I've come across this side of the unassailable, if a tad nichier, Every Day I'm Pastorin'. Basically it's pictures of ridiculous-looking animals and then commentary, often in the form of a dialogue between evolution and a bewildered observer.
If you haven't been following the conversation around Occupy Wall
Street, it's perhaps best summarized in terms of the Tumblrs.
First there were the 99 percent, who have been demonstrating in
New York and elsewhere for weeks.
