A short while ago I've received a request from another user to connect via facebook. Well, apart from the fact that I'm not very active on facebook, I'd definitely not like to provide any contact details on this site. That said, I was wondering whether there is some mechanism on this site whereby one can make this possible without the danger of unwanted contacts.
I notice from previous meta questions that one cannot send private messages because "this is not a social network." I can understand that (tongue in cheek), and I respect that. So this is not a suggestion for such a messaging system, but perhaps some other mechanism to take discussions to a different medium.
