instant messaging on SO SF SU
Is there any way one can engage in a private conversation with another user?
If not, why not?
That said, I think this meta site might benefit from some more social features. But that's really low on the priority list.
This has been asked repeatedly in the past and most often shot down by the majority of those who choose to speak up about it.
The reason being is that this site is not intended to be a social networking site. It is a Question & Answer site.
If the user wants you to be able to contact them, they will leave contact details on their public profile (such as my profile on SuperUser). Otherwise, if they don't make it available, that probably means that they don't want to hear from you (or anybody else for that matter).
