Camelopard, you forget the PM function. A poster can certainly regulate what goes on there. And you don't think some friends here communicate via email and other instant msg services such as Skype and Facebook? It would be naive to count them as separate from here, because the relationships formed here, can be cemented elsewhere, and carried back in, back and forth, no problem. It's quite close to real life in a lot of ways. Especially since more and more people are taking part in the picture threads, and other personally identifying topics. There are an almost unquantifiable number of factors at play here... almost as much as in real life.
