The Digital Story is a blog (with podcasts) dedicated to those wanting to improve their digital photography. The site is new, but the author claims he will explore a wide variety of techniques for capturing digital images. The site contains several options for adding the site to your RSS feeds.
Yahoo now has a podcast portal. The site does not offer a “main category” for educators, but the search function (series or episodes) generated plenty of hits.
The “in thing” is to use your iPod to listen to podcasts. The iTunes music store and access through iTunes on the desktop provides a convenient way to get the audio into your iPod. I must admit I don’t use my iPod in this way. Mine sits on my desk except for the “road trip” I have the opportunity to make now and then. Grand Forks is not the kind of city that requires the use of an iPod during the daily commute to work. I listen to podcasts from one of my desktop computers.
As portals compete for attention, I would suggest the advantage will go to the portal providing the best search features. iTunes has a different advantage in the integration with music content and access through the iTunes software, but in the long run may not offer the best search capabilities. We will have to see how capabilities develop around content.
