Adam Curry, the former MTV VJ, is the star of a new broadcasting medium. His show, Daily Source Code, claims some 50,000 listeners — but can't be heard on the traditional airwaves. Instead, it's a podcast, so-called because it's delivered via the Internet directly to iPods and other personal listening devices.
The podcast pushes the range of personal online rantings to something close to an international radio broadcast. And as NPR's Nathan Santamaria reports, the quality is low, but the hopes are high.
