I like the embarrassing arguments from MathOverflow moderators re. not closing Mr. Thurston's (vague, subjective, "not a question") question on MathOverflow. Nicely put by Georges Elencwajg in one of the comments: ...posed by somebody else, this question would have been closed within a picosecond. The rationale, ironically, being that professional mathematicians of quality would flee this site in droves because the question is "discussiony", "vague", "has no right answer", etc. This is the Matthew effect in all its glory: "For to all those who have, more will be given, and they will have an abundance; but from those who have nothing, even what they have will be taken away" (Matthew 25:29) Needless to say, I'm euphoric at the thought of Bill's participation in MathOverflow.
