I'm seeing a lot of new users on StackOverflow who are replying to me in comments after a question, either without mentioning my
@handle, or by using my
handle without the at-symbol, or who put a space after the at-symbol. (I tend to review my own activity history every now and again, which is why I notice it).
So, I propose that the commenting help (the 'help' link adjacent to 'Add comment') be open automatically for new users. Once they pass a trivial threshold of reputation (say 250) then it no longer opens automatically (hopefully they will have internalised it by then).
So, is this a problem that others have noticed? If so, what is the best way in which new users can be helped to understand the system during their learning period, when they are most likely to give up with it?
