Well, I've watched a fair few animes such as Baccano!, Steins;Gate (what's out of it so far), and Puella Magi Madoka Magica. And played several Japanese visual novels such as Kikokugai - The Cyber Slayer and Swan Song [http://www.escapistmagazine.com/forums/read/326.301706-Visual-Novel-review-Swan-Song].
But I've read only very few manga; The few volumes of Spice & Wolf and its counterpart Maoyuu Maou Yuusha available in English so far, and a volume or two of Higurashi no Naku Koro ni and Vinland Saga. And aside from sticking with those series, I probably won't delve all that much further into the medium.
As for your question proper, there are quite a lot of anime fans [http://www.escapistmagazine.com/groups/view/Anime-Fans] on the site. And also a (considerably smaller) manga group [http://www.escapistmagazine.com/groups/view/Manga-for-the-World] too, as well as one for Japanese visual novel games.
