"Podcasts managed by FeedBurner have an average of 33 subscribers, up from an average of 15 subscribers in February. If you discount the feeds with less than 5 subscribers, the average number of subscribers per podcast is 65.
In February, we managed 20 podcasts with over 100 subscribers and hundreds of podcasts with more than 10 subscribers. Now we manage about 20 podcasts with over 1000 subscribers and hundreds of podcasts with more than 100 subscribers. As we noted in our first podcasting report in February, a typical "long tail" is developing."
I'll take 65 subscribers on average for a medium that hardly existed a year ago.
