The SXSW Interactive Festival will offer more than 300 programming sessions on all kinds of tech-related topics. Like the creatives crowding into the Austin Convention Center and spilling out onto the streets of Austin, we're always looking to innovate and improve our product while finding the best way to disseminate the latest and greatest. In turn, one question potential registrants often ask is "What's new?"

For the geekiest of the geeks, we are happy to announce that five days of workshops have been added to the agenda for SXSW Interactive 2010. These sessions will allow organizers to provide more in-depth and more technical insight than is often offered in the standard panel format. Workshop titles confirmed for March 12-16 range from "Building iPhone Apps With HTML, CSS, and JavaScript" to "LBS 101: Geolocation on the 'Horizon'" to "The Ten Commandments of User Experience."

Here's the up-to-date list of confirmed panels, solo presentations, Core Conversations, readings, and workshops. Check back on Tuesday, Dec. 15, when we'll round out our full lineup with a final announcement. Questions? e-mail us.
