Google Base Trolling for Podcasts

Steve Rubel at Micropersuasion posits that Google is building a stealth podcast search engine. Google appears to be prompting Google Base users to upload and share their podcasts. Users are offered opportunities to bulk submit podcasts and are promised potential audiences of millions. A quick search of Google Base shows that there is a substantial number of podcasts available on it. This still seem like a odd way to go about building a podcast directory. Will keep an eye on this in the future.
