I wonder if silence would encourage users to be more independent when trying to solve their problems? That seems to be the way qtcentre.org operates. People will reply if they have an answer, and ignore your post if they either don't know the answer or the answer has been answered numerous places already. I personally prefer silence over a "RTFM" reply. IMHO there is less chance of confrontation As the old cliche goes, "If you can't say something nice, don't say anything at all."
"Please, loving community - How can I do this?" - Wonderful User "Dear Mr. User, " <- a detailed helpful answer that describes how, why, what, who, etc.. of their question. - Helpful Geek Dude "So, I just run this command then?" - Wonderful User "No, I said .." -> further explain the problems around what they are asking - Helpful Geek Dude "So I ran that command and this happened.." - Wonderful User "Are you fscking listening to me?!?" - Not so Helpful Geek Dude anymore.
