Awasaka Under the Bridge is alright, but it's very whacky. Classic Japanese style of humor, where everyone has lost their minds except for the main character. It's okay, good if you need something to watch.
The World God Only Knows is pretty recent (part 2 just came out), and it's quite entertaining.
12 Kingdoms (which is an epic quest to... kill some monsters?) is watchable, and entertaining (better than the average), but it didn't draw me in like a superb anime would. Same with Eden Of The East (which is about some weird, rich world saving system) and Zoku Natsume Yojin-Cho (which is about spirits).
Definitely recommend The Melancholy of Haruhi and K-On! Haruhi for its excellent story, and K-On for its (ironically?) excellent lack of story

. And Finally, Toaru Majutsu no Index or Toaru Railgun... something something... they are great animes, I enjoyed Railgun much more, the story developed really well, and the characters were great.
Gintama is a great quirky, smirk-inducing anime. It's like an IV of random events and japanese humor streaming into your brain. Too bad it doesn't work properly on my xbox
