I also thought Twitter sucked, but then I started using it. It's not bad really. First, you don't have to write anything. Second, if you don't follow anyone and you don't tweet, then nothing happens, it's not a magical 'the sucks machine'.
Yeah right. Except if you are logged in then it can track pretty much every page you visit on teh internets because every web page has to have tweet this and facebook that button.
I f you don't mind that, fine.
