I remember reading somewhere herein in meta some misgivings about the name “Mathematics Overflow”, the concern being that people surfing the web who happen to come upon this site may misundertand it (not reading the FAQ, of course) for being the kind of thing that se.math is for. There is another concern that I would like to point out: semantically “mathematics overflow” is close to “superfluous mathematics”. It may be only a question of time before this becomes genuinely embarrassing for the site.

Not to worry. Very apt alternative names exist. Here are two:

The Rabbit’s Burrow – the allusion being to the well-known joke about the wolf-eating rabbit, of course.

House for the Feeble-Minded – the allusion being to the joke/subterfuge used in Isaac Asimov’s story “Profession”, of course.

I’m not saying that there is any hurry about it. But then, there “wasn’t any hurry” about preparing for Y2K, either.

Yeah, I agree with @Yemon: this seems like a waste of time. It's long long past the time when we could plausibly think of alternative names, and even so, these suggestions are not useful ones.
