I've been hounded for at least a year now to get it, personally I don't think I ever will but there's this nagging sense at the back of me saying that I will.
But the thing I have about it is that I reckon it's a massive waste of time. From what my friends get up to it's a 'fantastic socialising tool' where everyone comments about absolute shit all the time (well this is coming from my perspective as a 15 year old) and plenty of people here are at least double my age and use it for different things, notably finding old friends again.
Personally I can find two good reasons for it- finding old friends (eg friends from primary school) or talking to girls (:)). However I think that every other reason for it is a waste of time, and for me the cons completely take over and wipe the pros off the map.
Now my social life isn't great (actually its more appalling lol) and I wonder is that due to me not getting FB and either not finding out about things or just not being connected?
