I asked a question and got 5 valuable answers and 6 "up" votes. Then someone commented saying that my question was argumentative. A second commenter disagreed. The next day, the first commenter plus four other users, who neither answered nor commented, voted to close the question.
So, gangs of friends with enough reputation can go around closing questions at will? That's stupid. Votes to close are already effected by the up/down vote system of viewers. A separate vote to close system is unnecessary. A broken one dissuades new users like me from participating.
I vote to remove voting to close.
Update: @Pekka and @Diago have convinced me that the "gang of friends" scenario is unlikely and that, instead, individual high-rep users voted to close my question. But the core problem remains. 5 users voted to close while approx 75 viewers either voted up my question or provided valuable answers and comments. That just doesn't seem right.
