Why did I get -1 vote for both questions I asked regarding Stack Overflow? Is it something like bullying on this site?
The first rule of Stack Overflow is that you don't talk about Stack Overflow on Stack Overflow.
If you want to talk about the site itself, please don't do it here. Visit our meta-discussion site where you can talk about things like what questions are appropriate, what tags we should use, suggest a feature, or generally discuss how Stack Overflow works.
OK it's not quite the first rule, but it is mentioned quite early on in the FAQ.
Questions about Stack Overflow is what meta.stackoverflow is for, and that's why we are here now.
