I Don't Plan to
I'm here so anyone who's interested can read my stories here.
I'm on Facebook only because someone I know 'friended' me so I set up an account and we're 'Friends'. I don't even make an effort to do much there.
I don't have a myspace account and I don't plan to. If I had kids I would to keep up with them.
So I agree with the others in this group. Twitter is pointless.
