People that don't jump on the latest bandwagon aren't luddites - they've just seen the hype before and don't subscribe to the latest fad.
I'm a fan of Facebook, because I can catch up with old friends. I hate MySpace because it's a visual abomination and I don't have the time to sift through the cr*p.
Flickr's great if you're into photography or just looking to document your life. Then there are a multitude of other sites that keep you up to date with everything you could ever wish for...
...except....
...I actually have a life that exists outside of the internet. To get constant updates on what my friends are doing is of absolutely no interest to me - if I want to know what they're doing at any point in time then I'll log on to Facebook. Or (shock horror!) I'll phone them and actually meet IRL.
I have my own life to lead. Twitter - to me - is just irritating, intrusive and downright pointless. If I'm windsurfing, do I really care if my mate is shopping for a donkey pouch in Ann Summers?
Micro-blogging my ar*e. Twitter has it's niche but if you want it then you should pay for it IMHO. Then see how the usage drops...
IT? because the OP is obviously 12.
