Never bothered... I spend most of my days in front of a computer anyway (at work) so I try to minimize my computer usage at home and do something else instead (like excercise
)
I even try not to look Joe related stuff at home from the net (cos' I can do it from work... at least for now) So I really have no interest spending countless of hours on Facebook ( as I hear its highly "addictive"), but my girlfriend spens more than enough time in there for me
so no facebook/myspace/whatever for me... If I have to get in contact with my friends, I call/text message them...and those that are aboard I'll just hit an e-mail...
But as I've heard it is a good place to get in contact with old friends and people you used to know and see what they are up to... but it is also possible to peek into others lives who are dumb enough to not put the filter/blocking on...
Some people I know who update their profile everyday are even stupid enough to post when they are away from home
... its like open invitation to burglars...
