I only use mine to keep up with family that lives further away. Otherwise, I don't touch it these days. I agree that 99.9% of the crap on there is pointless.
i have neither f*book, nor twit'r. not for any reason about either of them, but rather no reason nor interest TO do so. they just have nothing to do with anything i'm interested in or get on line for. and if corporate media ever completely usurps the internet, i will no longer have any reason to be on it at all.
