Check out Best of Wikipedia (why is all the good stuff on Tumblr? Maybe I should be on Tumblr? Would this site be better and cooler if it was on Tumblr?). It is what it sounds like, and it updates regularly with fun/interesting/kooky stuff. I like the one linked below, highlighting differences in languages’ interpretations of colour gradations (although it says a weird thing: “Also, some languages treat light (often greenish) blue and dark blue as separate colors, rather than different variations of blue, while English does not.” Wouldn’t that be turquoise in English?).
