Pandora made its interest in podcasting clear several times this year. Now, the music-streaming company is ready to announce the "Podcast Genome Project," a tool that's both a cataloging system and recommendation algorithm for spoken audio programs. Much like the company's existing Music Genome Project, which categorizes music on hundreds of characteristics to make recommendations to listeners, the Podcast Genome Project (which I'm now abbreviating to PGP). uses both human curation and scanning technology to help users discover podcasts. As of today, the PGP is in public beta.
