Is it just my perception or is there a greatly increased frequency of votes to close as "off topic" for perfectly valid questions?
As an example, why in the world would you vote to close...
...unless you're just being a jerk?
I find it very disturbing that people with reasonable and honest questions about mathematics are being pushed out by a few power mad users. Some ridiculous users seem to enjoy voting to close questions just because they can.
Ok. Now I've vented and gotten that out of my system.
