It seemed clear that PodShow and Odeo wouldn’t have the podcasting scene to themselves for long. To wit: Yahoo Podcasts launches tomorrow (Monday) morning. The site isn’t live as we write this. From the description we received, the service will allow people to “find, listen to, rate and review” podcasts. The service will work with iTunes, Yahoo’s Music Engine and Windows Media Player. What it doesn’t have – and where Odeo and PodShow hope to excel – is helping people create and promote podcasts. That’s apparently forthcoming, though.
