As far as I know, Stack Overflow is positioned as a bit social networking service. So, is there a friends system here? Or at least a private messaging system?
What is meta?
- Any Stack Exchange user can ask a question
- The community provides support, votes on ideas, and reports bugs
- Your voice helps shape the way Stack Exchange operates
....no, no we aren't. If this happens, go ahead and send someone over to shoot me.
I kid, but no, social networking isn't what we're about, there are already sites for that. We're about the content, not the user.
We're all for promoting the individual user, showing off their achievements and awesome answers and such, but not making them a target for tons of private messages which would end up as "hey, answer my question??" Remember, everyone here is a volunteer. Keep in mind that's one of several dozen "bad" scenarios introduced by things like a private messaging system.
