What proportion of questions posted on here are:
(a) Asked by undergraduates looking for help with their homework?
(b) Postgraduates that have grown up with google and have difficulty finding information for themselves ?
(c) Well formed?
(d) Interesting research questions?
The four options are not mutually exclusive and it is a genuine question. The corollary is: how do we eliminate (a), minimise (or correct) (b), avoid the complement of (c) and maximise (d)?
