I've wished for this feature! I don't think there is thought. There are some great people on here that I've wanted to discuss various topics with in more detail, but it's not possible with the format of this site.

No, I don't think so. But I don't think people get offended if you contact them offsite via Facebook or Pinterest if they link it in their profile, or drop an invitation for them to contact you via something in your profile as a comment on one of their answers.
Some other Stack Xchange sites have a chat room, which would be cool, too. Interacting in realtime with Paleohackers would be awesome.
