Seems my Anime/Manga interests have been fading as of late sadly.

Aaah, I know how you feel. I can't find a lot of good material lately. The newest I've gotten into is Claymore and that's only because for some reason Paradise Kiss just stopped with only one volume left to the end (what the hell?).

My guilty pleasure is pretty much any romance or school life anime...fricking escapism in media...
