Allthetropes: a fork of tvtropes
NSFW, if by "not safe" you mean "you will waste your day on it and risk losing your job"
I didn't know that there was a fork of tvtropes, with a Free license (as opposed to the NC one that tvtropes has moved to):
allthetropes.org/wiki/All_The_…
I'm not sure if I want to keep an eye on it or if I should *stay*away*from*THAT* just like the original one.
