i joined Facebook and am really bored with it for the same reasons, friends broadcasting pictures and descriptions of nights out etc.
I think Facebook is for the younger generation and those with plenty of time on their hands, I simply am too busy to fart around with keeping up with the trash on it.
I am on farmville but got bored with that too as it doesn't 'do' anything. I am 39 years old but my same age wife loves it, though she is younger minded than I am.
I am the 'grumpy old git' in the household.....
