Where can I read what kind of questions that are appropriate to ServerFault?
One could think About page is such a place, but it is not.
I have a couple of questions that were poorly received. I can see why the first one How to set environment variables was downvoted (it's a basic Linux and Unix question, appropriate for that Stack Exchange site), but I can't see what wrong with a question on FAT vs NTFS in a KVM guest. Therefore, I can't understand how my questions can be improved, so that they would be received better (which I need now, that I am autobanned). Also, it makes me very afraid to ask questions in future.
Anyway, what is the right thing to do when my question is poorly received (e.g. the linked two). I could delete them altogether, but then I can hardly see how I could get positive reputation: I imagine I would need to spend a lot of time learning untill I can answer any questions like the highly competent people that are getting upvotes on this site. Asking the questions that don't suck looks like a more realistic proposition short-term.
