Useful for illicit affairs, drug deals, prostitutes, and probably a few other things too.

I really believe this could be one of the most interesting subs in reddit, but the major issue I have with a lot of the submissions is that I really wouldn't say I learned anything. I will preface by saying that there is an /r/Trivia, and I would like to propose the following guidelines to help you decide whether to post there or here.
I realize I may be kicking against the pricks here, and that it's probably too late to stem the tide, but a fully functioning TIL and Trivia separation would be the bees knees to me. If you think like me and it looks like this plea won't work maybe we should make /r/TILhoworwhy and start from scratch.
Edit: Based on up/down count vs. comment content I've come to two conclusions:
1.) A little more than half of TIL's subscribers agree with me.
2.) Those that agree with me are not the ones who actually contribute or discuss in it.
And so I say: "Farewell, TIL, it was nice while it lasted."
To which the commenters reply: "Good riddance, pretentious Fucktard."
And then I'm sure I made the right decision.
