Someone yesterday asked me: Do you know anyone who actually uses Twitter? The question was rhetorical, but the answer was yes. Even we Twitter (sometimes).

But here's another interesting example - USA Today blogger Whitney Matheson is using the service to "Twitter her day." Normally I would be loathe to link to someone that posts about the minutiae of her life, but its Matheson's very personality that has made her a successful entertainment blogger in a crowded sea (though the USAT affiliation can't hurt). I'm sure the people who follow her blog will follow her Twitter stream (if that's what it's called, kids). Not sure there's revenue in that, but it's not always about revenue.
