I'd like to ask you to check your aggregator and make sure you're subscribed to the permanent feed, which is http://feeds.feedburner.com/teachnology.
It's the one that's now available by clicking on one of the XML icons.
I was making a new feed for each show. DOH! Silly me.
Thanks to Russell Holliman of the Treo Podcast for fixing the cluster of feeds I had generated at feedburner and developing one feed for the podcast and one for the show notes. Russell, you da man!
I will delete all other feeds shortly, but we want to make sure we get all our listeners over to the new feed first.
