I always see Stack Overflow users giving -1 to new users' questions. This is not how you welcome a new user to the community. A new user does not know the rules yet.
I suggest that if one wants to give -1 to a new user, you prevent that and ask the downvoter to write a comment instead. new user = 2 first questions
I see the credit rating on my question is now at -9? My question, is she not well formed or formatted? If you don't agree with the content of a question do you down-rate it? If an Ubuntu user asks a question that might not be reasonable, will you also down-rate it?
No. You post an answer that will present your thinking and correct him? I think that is part of the problem. When you first go to a community like Facebook, and you don't know the faces, you don't feel like any of those people are your relations. Newbies exist here as well, especially in a professional community.
First, welcome the new user in more appropriate way. And most importantly, force them to see/read how to post a good question.
