An old uni friend who know lives in a different hemisphere from me has sent me an email asking if I would like to be one of his facebook friends. He was a nice guy who I lost touch with unfortunately and I can see the benefit of saying hello on his page but I have to join facebook as well. I have always been reluctant to join facebook as it always seemed a bit of a (insert a derogetory term here which rhymes with plank). But I don't want to offend an old friend. So if I join will ANYONE be able to see my page or can I restrict who sees it or will all the millions of facebook users be able to see it. I also see that tehre are many viruses, phishing emails and worms I can pick up from it. Also what about identity theft which I hear about. So should I join face book and am I worrying too much?
