Any way to send a personal message to another user?
I don't expect that this is going to go over well here based on the only other question I've found related to this topic, but here goes....
It seems that some sort of user-to-user messaging is the only major "social/community" feature missing from Stack Exchange. Would there be any value to adding user-to-user messaging outside of the context of questions, answers and comments?
What are the reasons for and against including user-to-user messaging on SE sites? Note that the lack of the feature-request tag is intentional. I'm not requesting that the feature be added. I'm just interested in the discussion about it.
