Thought I ought to point out that as well as here, I've been over on Facebook for ages now (which I mentioned before), & Twitter now too. Here seems a bit quiet recently, which is a shame, as I still think here does some things better (including listening to music, which is pretty essential for me).
Facebook is very good for Groups, which then send you emails about stuff. On the music side of things, thats its best feature really. Probably best I don't overbroadcast my address over there, as its also more about personal stuff I think than here is, but you'll be able to find me if you want to...
Twitter is a bit overrated, but it IS interesting reading what comes through from people, at least once you've joined a good set of them up (& quite different ones on there to Facebook to Myspace, which is also part of the reason I'm keeping up with all three sites). I'm not posting as much as I might, but hopefully I also only post vaguely intersting stuff, as opposed to one-word replies etc. http://twitter.com/philblackpool
It should also be noted that its interesting seeing which of these sites survive & which get abandoned (or at least aren't popular in this part of the world)....anyone remember Friendster? Then theres Bebo, which is scarily open to kids...etc etc...
