If you’re interested, I’m liveblogging the annual Inc. 500 (now 5000) conference, which starts here in Washington DC tomorrow. The first few “preview” entries are up here. More to come. I’ll also be Twittering from the conference floor. (Cf Is Twitter a Waste of Time? No, Says Inc. 5000 CEO.)

It’s a busy weekend for conferences, the kind that makes me wish I could be in several places at once. Web 2.0 Expo has started in New York. And this year’s blowout BlogWorld starts Friday in Las Vegas.
