ok maybe Hate is too strong a word.... sometimes
But it seems to turn people who are perfectly nice, normal and fun to be around in real life into annoying twats online
and honestly, there are one or 2 of my previously close mates that i just can't be doing with as much anymore as they are so annoying on facebook
there are the braggers "how great is my life" showing off about new cars, new houses, new home stuff, holidays, nights out, weekends away etc etc
the miserable fuckers "life is so shit " and sometimes a simple " :,( " as their status
the highly cryptic status posters, ie "one of my so called friends has really let me down" or similar, cue loads of comments "whats up hun" etc etc and the perpetrator of the status either totally ignores it or responds "i'll pm you hun"
the ones that use it as like, a social bragging platform, ie "so and so is at (super cool bar / restaurant / club that kind of thing) with so and so and so and so" then they all keep commenting on the status and talking about it afterwards
and yes, i know about the "Hide" button. but quite honestly some of it is compulsive reading 
and the worst of it?? I Am Probably Guilty of MANY of these facebook sins either recently or in the past. 
i just think it brings out the WORST in people. yet - what did we do before it? i can't remember life without it and I am 32 ffs not 15!
