I stopped into the iMeme: The Thinkers of Tech conference, put on by Fortune magazine yesterday and today in San Francisco, and ran into a passel of the Internet regulars, talking about–you guessed it–the Internet.

You got your John Chambers of Cisco, you got your Sheryl Sandberg of Google, you got your Marc Benioff of Salesforce.com, you got your Jeff Weiner of Yahoo–and you’ve got yourself a digital partay.

A lot of people were blabbing about the latest bubble rumor that Microsoft was considering offering $6 billion to purchase Facebook. Yes, the No. 2 (by far) social-networking company that could, making the definitive leader MySpace worth, like, a kabillion.

Here is my little video of the event, as I chat with conference organizer David Kirkpatrick and Fortune magazine editor Andy Serwer (with whom I went to the Columbia University Graduate School of Journalism, where we both did precisely nothing).

I also play a little word association–$6 billion, being the key one–with Microsoft’s Yusuf Mehdi and the obviously-weary-of-me Facebook PR maven Brandee Barker.
