The first and only invitation into a social network I had ever accepted was Hi5. And I don’t use it very often. From time to time I add a friend, which is someone that I know from real live! Not someone that I’ve never seem or talked with. It may be not a friend in “real live” but at least is not a total stranger.
Today I have joined Facebook. A friend showed it to me some time ago. He uses it to share his Erasmus photos, so now I’ll be able to see them 
However, I try to be cautious about the information I share both in Hi5 and Facebook. Don’t give your life away in a website.
