@MikeOToxin no? Magazines should have standards for their posts so that a community can be formed and grow around those principles. The principle of 'just post whatever you want' doesn't encourage much beyond post anything. The only real restrictions on posting in the rules are: no baiting, promoting agendas or self-promotion.
There is nothing there on how you present what it is you've learned beyond 'start it with TIL'. There isn't even a hard requirement that you link to the source, which makes no sense.
Requiring users to actually link to a reliable source to back up what it is they've learned, and to present the knowledge in an objective and readable manner should be a bare minimum.
