It is a Wiki of the devices used in fiction writing.
That's right, TV Tropes is actually another Wiki; just like this one. (But worse.)
There is no such thing.
It gets mentioned very often, mainly because of BL or SR. If you reference a trope and link it when he's around, BL will get mad because he feels you are inferring he wouldn't know where it came from. He is a trope connoisseur.
All that time... Gone.
