PodNova is both a free web 2.0 service and a free client application that works with iTunes and several other podcatching software programs. As a web 2.0 service, it provides a method for not only subscribing to podcasts but also sharing those subscriptions via a RSS feed and an OPML file via a web-based interface.
Podnova reaches out to meet your podcasting needs – It’s a place where you can:
manage your podcast subscriptions, discover new podcasts, find new podcasting software for Windows and for your mobile device, playback the podcasts you’re subscribed to and combine them into playlists and browse a vast library of software for various platforms
All without ever switching to a different application or opening another website.
