Does anyone think these are worthwhile?
Not long ago, somebody on one of the many list-serves that I'm on persuaded me that I should create a Facebook account for networking, blah, blah. More recently, I said to hell with it and also created a MySpace account. It's all free, after all. At the moment, though, having had a look around on these sites, I can't actually see a lot that I'd want to do with them.
