I actually like the strict style of Stack Overflow.

And i find the "Not Constructive" to be exactly that.

Yes, it can be annoying when a question is closed and you really wanted to discuss it, but the rules are quite clear on what is and is not classified as "Not Constructive", and the discussion should just move to some of the discussion threads instead.

And i don't know what you interpret as negativity? I have never seen unfair or non-objective use of moderator functions?
