There's a HOBOTOPIA feed on twitter. It's found here. There's also an account maintained by Aloysius, which requires significant effort to locate. I also twitter, though I don't like to talk about it. That's the first rule of twitter.
you have perfectly illustrated the adage there.NOM (smirk)
Sorry, I don't get twitter. I think the current Doonesbury comics on the subject cover the problem pretty well.
