This has nothing to do with communicating with them. At least not my suggestion. It has to do with basically seeing where they are. Lets say i'm in announcements and you are in Perl and Cgi, and I go to who's online and see you're there viewing a post. I'll click the link and go to that exact post where you are. Not really about communication but seeing what you're up to.
