I'm probably well behind here and it's quite possible that I'm going to get leapt all over, this is after all the Internet, and there's no room for Antiques Roadshow here. I finally got around to actually looking at TV Tropes, a site that usually features pretty high up on Google search results. Although it specifies TV in the title, it actually self-admittedly deals with fiction as a whole and as such is an incredibly useful resource.
The combo of a wiki-style linkfest and the inoffensive humour makes for pretty strong 'Oh shit, it's 3 in the morning.'isms too.
I'm debating it's actual use in my work, but you never know.
