What is the relevance of “ @ “ in comments?

I often see @user here and there in the comments.

What, pray tell, does it mean and what is it used for?

Do you mean @username: ... as used in comments? That is just to signal who the comment is for, especially if this is not the original poster.

    But, of course, it is broken, because users can freely change their display name...not that I let that stop me from using it. Commented Oct 13, 2009 at 21:38

    You need it because comments move up as they are voted so it's not obvious that you are replying to the immediately preceding poster Commented Oct 14, 2009 at 4:05
