Yes, I have a Twitter
account, and post to it.
The problem with Twitter and Myspace, etc. is that oftentimes strange people you don't know sign on to follow you. With Twitter, I just blocked three users who: A. just opened accounts this past weekend, B. had the exact SAME user graphic, C. posted random junk on their accounts for filler, and D. didn't seem like people who read/wrote m/m fiction. A bunch of weird sockpuppets? Who knows?
But if I don't know you on Twitter and can't figure out why you're following me, yeah, I'm gonna block you.
