I don't hate it as such, but I don't understand or 'get' the appeal to be honest.
A relative (exitedly) showed me their page once, and I kind of felt a bit dissapointed that all the hype about FB, just amounted to a page with some pics of people I didn't know with some comments about things I was never part of, so made no sense to me; why don't they just pick up the phone or arrange to meet if they are such good pals?
Some people treat it as a 'keeping in touch tool', with people they rarely see in the flesh, and that's great, but there are others who treat it as a 'social badge', "look how many 'friends' I have on facebook"; which is fine, but there's no need to go on about it and consistently say "you should get on Facebook" or "why don't you have a Facebook?".
I'm also, (probably naively) suspicious of the internet, so putting my personal info. and things I do on a weekly/monthly basis (or whatever people do on it!), I find a bit disturbing; it's 'there' for anyone (in your friends malarkey) to see; I don't want (potential) people having access to my life 24/7.
I have a mobile phone and email, but I don't use either like the 'average' person uses them; they are there if I need them, but they don't rule my life, nor do I need to use or check them on a daily basis
Come to think of it, maybe I do hate Facebook!
I watched 'The social network' recently, don't know how 'true to life' it is; but, if there is any truth to it's conception, it's quite ironic........
