I just saw another question with the limit of $(1 + 1/n)^n.$
A few months ago, somebody asked some other multiple repeat question, I wrote to check any of the last 137 times it had been asked. he assumed I was joking, and I had indeed made up the number 137.
Feature request: along with individual favorites lists, could we have (maybe as an FAQ choice?) links more precise than keywords, of questions that are really about the same thing, in the judgement of senior users i suppose. Maybe a list is kept, 10K people add links/question numbers to it, when it passes 100 questions it becomes visible to all users. Again, 10K users propose new topics that seem to be repeated often. I suspect this can be done within the existing software, and it does not need to come down on the moderators.
My temptation is to blame the kids asking, but there is enough variety in wording, and enough difficulty searching with Latex, that a people-powered list of hugely repeated questions seems worthwhile.
Apparently this is at least the fifth time this was asked. Sigh. I don't see this as likely to be a divisive issue; nothing about whether these questions are good or bad, no mention of closing.
It's different on MO. Searching actually works there, as people know enough to use the standard terminology for a topic. Kids wanting help with homework use idiosyncratic language, forget hypotheses, and so on.
added: let's see, sometimes the wish is to make a set of really good canonical answers for repeat questions. I think there you do have some potential disagreements, plus there really is tremendous variety in what the kids are able to read and understand, despite the possible similarity of the questions. So I am emphasizing a list of questions/answers that had already happened in the ordinary course of MSE use.
