There seem to be some nasty rumors going around about LJ and its possible demise. I certainly hope that doesn't happen! But one of the alternate blogging sites I saw referred to was vox.com and I've set up a site there too:
http://bibliotrope.vox.com. I haven't actually even posted there yet.
I also decided to try Facebook, but am not enamored of it; it just doesn't seem like my style of thing at all, but I was curious. I am listed there under my real name. I'm not at all sure I want to try MySpace either.
