Stuff with lots of B-through-Z-list supervillians, especially big gatherings of obscure supervillains. I love seeing a panel with 20 different bad guys and trying to figure out who the hell they are.
Scenes from before things went sour like Cassandra Cain being awesome or the Young Justice girls being awesome and funny.
Obscure but sweet superhero (and other) OTPs. Make me go "d'awwwww..."
Weird Japanese horror manga in the vein of Fuan no Tane. Some Junji Ito might be good.
There was an awesome series of posts about Maho Sensei Negima on the original SD. I'd like to see more of awesome/funny/sweet from Negima. (Are those posts archived somewhere maybe?)
Current or classic manga that are similarly awesome to Negima. Show me old school stuff that got you into manga in the first place.
Empowered, or other fun stuff from Adam Warren.
Porn, preferably funny stuff like the Red Crab of Communism from the original SD.
