Presently, it may well seem to users who are not yet familiar with MathOverflow
that flooding the site with questions is desirable and encouraged behavior --
at least this is what the point system appears to suggest:

  - an upvote on a question adds more than twice as many points as
    a downvote takes away, which can make even questions with negative score
    yield points,

  - one can get an unlimited number of points for questions, also if
    one doesn't answer any question of someone else, and

  - neither questions being closed as off-topic nor posts deleted
    for reasons of moderation nor flags "cost" any points
    (except for spam flags, but these are not applicable).

Do people see a problem here which should be addressed in some way?
