The Bill Gates media onslaught continues tonight on the Daily Show, where the Microsoft chairman is scheduled to talk about the work of the Bill & Melinda Gates Foundation, following the release earlier today of his annual letter on the state of innovation, the economy, philanthropy, education and global health.

It's also a chance for Gates to redeem himself, following his first appearance on the show three years ago. Back then, not only was he talking up Windows Vista, which would soon reveal itself as a clunker, but he also surprised host Jon Stewart and the audience by standing up and walking off the set before the show actually went to break.

It was enough of a shocker that Stewart returned to the subject the next day, poking a little fun at Microsoft and Gates in the process.

Presumably someone will whisper a reminder in Gates' ear before today's taping, or more likely Stewart will mention it during the segment. But in any event, chances are that his repeat appearance won't come with an early exit. Check back tomorrow for highlights.
