From what I can see of social networking there is 1 (ONE) good reason for NOT going anywhere Near Twitter, Tweet FaceBook etc., and Thats Security!!! Have a scout around the Net for related IT Security issue's. That alone is enough to Put you off!! Meantime I also agree wholeheartly with Alan!

I have better things to than twitter, tweet, facebook or crap on about what I had for breakfast, besides there is a much better social activety called communicating (talking) face to face and if thats not possible, a phone call or an email does the job! etc etc ... Bla Bla Bla
