I see here on Stack sites that tag names join multiple words with a hyphen. What, exactly, is the purpose of that? As long as my syntax is right, what does it matter if I'm searching for "multiple word" or "multiple-word"?
A question about
egg-cups is not the same as a question about
eggs or one about
cups. An egg-cup expert might want to see questions about egg-cups without being swamped with stupid questions about other kinds of cup; an expert on paper cups might want to ignore questions about egg-cups.
