Wes Felter and Seth Dillingham are both skeptical of audio blogging.
The bottom line, as far as I’m concerned, is that audio is too slow of a medium for imparting information. I can read text much faster than I can listen to audio, which is why most of us only listen to spoken audio when we don’t have the option to read, such as stuck in the car or while exercising. Plus, as Seth notes, it’s difficult to reference specific parts of an audio file.
Adam Curry has really been promoting his Podcasting efforts, whereby audio would be downloaded automatically overnight to your iPod. Maybe it will catch on, but I think there’s a reason we tend to send each other text e-mails rather than record voice messages and send them along as attachments.
Clearly, audio does have its place, especially for interviews or for newsworthy events. But just for straight blog-style commentary? I just don’t see it.
