Neither - not Myspace and I hadn't even heard of Bebo. I don't blog either. I chat with a handful of people on MSN (mostly my family) and I can talk on Skype with some family members - particularly my brother in Paris and my nephew in the UK. Every now and then I get a Skype message from some stranger, and I chatted with one (didn't talk) for a while, but he creeped me out a bit so I blocked him. A lot of them seem to be guys in Middle Eastern countries looking for a woman, and I don't bother with them.

Otherwise, the only other forums I go to are The Annexe, of course, and a couple of tech forums, which I sometimes read but haven't yet posted to - Ubuntu Forums and Whirlpool Forums.
