Anime Tropes etc. website

[chomiji]

I have no idea how good or accurate this site is, but it's pretty entertaining, and of course most of it is valid (or invalid, as the case may be) for manga as well. You can find entries for things like the ever-popular paper fan of doom (wielded with such authority by Sanzo in Saiyuki, among others), individual shows (including Fruits Basket and Bleach) - with notes about which tropes each includes- , and character types, like the Wrench Wench and the Idiot from Osaka.

It's also a Wiki, so if you're into that, you can help build it better, deeper, and more complete.
