I don't think we need this tag at all. Does anyone have any arguments in favor of keeping it?
This falls into same category as Klein bottle or Sorgenfrey line. We probably have a few tags about particular topological space. I think such tags might be useful. In particular, Cantor set is frequently used in real analysis. (Maybe posts about Cantor function could go into the same tag - they are closely related.) — Martin Sleziak33 secs ago
Maybe. I'm not sure that those tags are useful either. They don't give you anything that the half-working search system couldn't give you easily. — Asaf Karagila15 mins ago
I've made this argument already (@Martin linked to it), but it seems that the community's opinion (or at least, the people who browse meta) is that such tags are useful. — Najib Idrissi4 hours ago
