This is not to say that most of what is closed shouldn't be closed. But your existing policies consistently drive away conversation that I'd like to be involved with, and contributers like me.
As a concrete example, I'm quite sure that my most upvoted answer on SO is on a question that would be instantly closed and deleted under current guidelines if it came to the attention of the SO policy lawyers who volunteer to "moderate". See http://stackoverflow.com/questions/93526/what-is-a-y-combina... to verify.
