"Because anyone with more than 20 'friends' on MySpace and/or Facebook is kidding themselves."
Oh my! By your defintion my family are "kidding ourselves". Let's see shall we?
My step son uses it to keep in touch with REAL PEOPLE he meets at music festivals and to make their camping arrangements at the next one. Hundreds on his list.
My wife uses it to keep find REAL PEOPLE from her time living in South Africa and as a method of swapping photo's with not so far flung friends in the UK. About 70 odd on her list. It's also useful for finding out when said son is away for a few days so that me and the missus can plan a weekend away ;-)
I have only 26 friends on my list - all ex military types who for one reason or another lost contact when one by one we left the services. Believe it or not THEY are also REAL PEOPLE. (I'm sure that most of them have ot get the ir significant others to the typing for them though - last time I saw them, most of them would onsider a keyboard nothing more than a blunt instrument for despatching the nearest <insert latest enemy of choice>)
Facebook is a tool and, like any tool, if used safely and with due regard for the inherent dangers that the tool contains, it can be a bit of fun. It's a laugh for God's sake.... It's also a little more efficient than Royal Mail and a lot cheaper than stamps. Has an added bonus it has Scrabulous (for now) and Scramble too :-)
Why are you moaning about something you're obviously not interested in personally? Maybe if you took your blinkers off and broadened your horizons for a while, you may find something that you ARE interested in and leave everyone else alone.
See you in another life, Brother!
