instant messaging on SO SF SU
I have just had the experience of asking a question on server fault. I then was informed that it belonged on superuser. So I deleted the question and asked it there. Now a fellow who was educating me about correct usage of these forums i.e. the correct place to ask, different types of questions, then came over to superuser where I added the question and left a comment, which was directly related to my use of the system and not the question itself, thus detracting from the question, NOISE if you will. Don't get me wrong, I appreciate the comment but I felt it would have been better if the user could have clicked an icon next to my display name and it say, send this user a message.
Is it more that this would introduce hidden solutions and then this facility would detract from the intended usage of the site?
