There's loads of buzz about the new Late Night with Jimmy Fallon show, which debuts Monday on NBC.

The Biz reports that Fallon's co-producer Gavin Purcell is a geek who plans to apply the latest in tech to late night TV.

Purcell and Fallon have been doing a video blog.

Nicholas Carlson reports that the show will feature Twitter and Facebook.
And also Skype.

Carlson said: "Jimmy already uses Twitter and Facebook. Expect those services to be integrated into the production of the show. Also expect Late Night's writers to be generally aware that of that universe. Gavin says there are already comedy bits about Facebook written for the show.

"Just as we were sitting down to talk to Gavin in his office, another producer stuck his head in. Was 'that thing we did yesterday really Skype?,' he asked. Gavin told him yes, the video-conferencing in yesterday's test show was made possible by Skype technology."
