It may be convenient to have a tag to identify such generalized answers (created on purpose or not), and to present them first in lookups for duplicates in review. Generally speaking, we have ways to identify branches of mathematics and fine-grained subjects, but not much for the quality of questions (upvotes are hardly usable for this purpose), or the 'level' (as in approximate years of curriculum). On the long run, I fell there is too much material and to few ways to filter. — Jean-Claude Arbaut 1 min ago
