Guys like Mike Arrington, Reid Hoffman, and Max Levchin are all hanging out at Supernova 2007 this week in San Francisco.

From the site:
At Supernova, we attempt to answer “what’s next” after everything is connected. Supernova is the only event that assembles the most compelling people and companies from the converging worlds of computing, telecom, and digital media to put decentralization issues into meaningful social and business contexts.

In addition, Google, Yahoo!, AOL, Comcast, Verizon, Cisco, Sun, and IBM are all represented as well.

Some interesting topics of discussion include virtual worlds, user-generated content, online identity, social commerce and media, net neutrality, advertising, and copyright.
