There have been some meta post where users discuss whether or not a new tag should be made for riddles that go like this. The result was that it wasn't necessary. Recently, before I knew about the meta post, I created a riley-riddle tag, which was then removed by a user, sharing the link to the post in a comment.
Just 5 days ago from now, the tag was recreated by another user (I only found out today).
My question is, did the tag just pop out and everybody agreed that it was going to stay, or is there another public discussion somewhere else where some users decided that the tag should be created?
