I posted this answer on a while ago:
http://math.stackexchange.com/a/713284/131263 (my first answer on Math-Exchange).
I noticed it has turned into community wiki, which sounds good to begin with.
But then I read that I no longer get reputation for it, which sounds bad.
Can somebody please explain the logic behind this?
If an answer becomes community wiki, doesn't that mean it's considered a good one?
If so, why am I "punished" by being denied of any future reputation for it?
