From the official site:

Geek is Chic is a podcast, where technology is fashionable and practical. Nothing could fulfill this creed better than using the technology available in New Media and in web 2.0 to benefit such a worthy cause. We will be live and interactive throughout the entire 24 hours. You can listen to the broadcast, call in, and even chat on Talkshoe.com. We’ll also be showing live video footage during portions of the podcastathon using Ustream.tv. You can find directions of how to join us right on our website www.geekischic.org.

Rob will be on the show 2am EST and going until he falls asleep. You can find him streaming at Geek is Chic or his personal UStream channel at ustream.tv/channel/rob-blatt.
