I'd rather like to know who posts those great one-liners. When Twitter first boomed, I saw a lot of enthusiastic pointers to various famous people who were supposedly doing great twits.* I followed them and none of them were any good. I've found only one person who actually has the chops to be a good twitterer, and that's Mark Evanier.

*As long as it's called Twitter, I'm calling them twits.
