FB is a great business tool and I plan to set up a page for my business with a link from my website.
I reckon FB would be usefull for friends/relatives who may live interstate/overseas.
But to be used as a general social tool to show your 'friends' how good your holiday is or which nightclub you are off your face at is IMO a big fat wank.
I got on FB 2 months ago to allow my son to enter a competition which was rugby league related as this appears to be the only way to enter these days. I haven't told many people that I am on FB and if they attempt to be 'friends' I will ignore the request. The only 'friend' I have is my wife's best friend and I get her daily horoscopes on my wall everyday. When I work out how to de-friend her I will become a Nigel - and that's the way I like it.
I'm scotty88 and have a wonderful day.
