Need new series to watch, 4chan style

So guys, I'm starting to run out of anime to watch. So far I've been highly impressed by 4chan's ability to recommend great anime. Futakoi Alternative, Pani Poni Dash, and some others I got from 4chan's recommendations. You're saying good things about The Melancholy of Haruhi Suzumiya and Shakugan no Shana, so I'm going for those now, but do you have any other recommendations? Loli elements are a plus, but not required (altho expected from 4chan).

Well, I could try mentioning something even you might have heard of.  What about uh... must be something recent, hm, ten years... no impossible, lets make that twenty.

Project A-Ko. (one of the sequels, if not all, is superior, can't remeber which one)
