Hayore! Nayaruko-san! - very funny series (loosely based upon Lovecraft)
Saikano - great series, but VERY sad and depressing. (not sadder than Clannad: After Story)
Sankarea - romantic comedy involving a high school boy who loves everything zombies. Then he meets a cute rich girl who hates her life and wants just be normal... It's quite original and funny actually.
Funimation's website, and Nico Nico's, though I don't know if you can get Nico outside of Japan. It's a simulcast, so it shouldn't matter.
The Woman Called Fujiko Mine?Anywhere I can watch the new Lupin series online legally? I've heard it's great.
The Woman Called Fujiko Mine?
I really need to start watching that. I've heard that it's pretty good myself.
