One other vague objection I have is that I don't think people should make assumptions about the "level" of their questions. A [what-is] tag doesn't quite do this, but it's a move in that direction. One of the awesome things about MO is that people from all points in their careers, and I worry that a [what-is] tag might start people on the path of binning questions as "below me" or "above me" before even reading them. Part of the point of MO is to bring together people who think they have hard questions and other people who think those questions are easy.
]]>I plan on posting one such community wiki question as a one-time trial and create a 'what-is' tag. Any suggestions or tips on the best way to ask?
