Don has guests on a number of his shows, and it definitely helps keep things moving during those segments. I think you've hit on something, though. A co-host--even a rotating host--would probably add more interest to the show.
Since Don was on BOL recently I decided to try out his podcast The Digital Home. I was curious as to how many of you had listened to it as well?
Since there currently a forum for the Digital Home Podcast, I figure I'll post my thoughts here. The podcast needs at least one more person on it! I had downloaded the last two for my commute to work and was thoroughly disappointed. An almost forty minute podcast that comes across like a one man rant?
As much as I love a rant, the podcast seems to be very long winded for a single host. I am not sure if anyone else noticed the same thing after trying it out. For now I've unsubscribed from itunes. Sorry Don, if you pick up a co-host I'll surely try you again.
