Online Profile...

I've been reading Bill Thompson's Bill Board on the BBC news web site.

Apart from feeling old, I thought; I want one of those..an on-line profile.. what ever those is..

There are quite a few social networking sites out there, but which is the best? I was talking with some friends at the weekend and they said dont use facebook.... I would have argeed if I knew what facebook was.

So what are the 'cool' sites?
Is myspace still cool? What about friends reunited? and twitter? what the hell is twitter..
Are blogs still cool??

Sometimes my head hurts too much....
