I asked a question about JavaScript on Super User and eventually deleted the question (as people voted to close and started downvoting). And for that matter, the question did not warrant an expert level answer (or comment).
My question now is, if such questions are off-topic, why have such tags on Super User in the first place?
(P.S: I do not know if Stack Overflow came first or Super User came first. So if such questions were being answered on Super User in the beginning and the tag stays only to keep those older questions alive, pardon my ignorance.)
