On not getting it in the slightest

I haz done it. But I'm failing to see the point. Several years after everyone else I now have a facebook account.

But, er, just what is the purpose of this fabulous must have thing?

No, really, I'm serious...
So far all I've worked out is you put the name of your real life friend in the top box, and thump search. It then brings back lots of results that aren't your friend at all. You then do this several more times, narrowing it down by inserting their location, weight, DNA structure etc, and you finally find your friend.

It then says click here to add them, so you do, and fill out a captcha, and then it says they will think about it, oh and here is a massive list of people you don't know remotely, but are they your friends??

After half an hour I've found oh! four friends, and my sister Idiot Girl. I clicked block on idiot girl, as frankly knowing her in real life is waaaay too much.

I consider myself to be good with all this interweb stuff, having been online since 1995.

I can remember mosaic browser, then there was that new fangled netscape thing. I had a hotmail account before it belong to microsoft... And I had a 28.8 modem for the speedz..... so why don't I have a clue what the bloody hell this social networking guff is all about?

If anyone can tell me what happens now, and when the excitement is likely to start (So I can wear my brown pants on that day) I'd be happy to hear from you...
