Amber MacArthur and Leo Laporte interview Kent Nichols and Doug Sarine from Ask a Ninja on Inside the Net | TWiT.TV.
This was a really fun interview. I like being able to sample this podcast online, instead of having to subscribe and get delivered a tons of shows that I might or might not be interested in.
RSS and subscriptions are good to get shows that you know you want to listen to or watch, but subscriptions to shows that you don't normally watch just fill up your disk and use bandwidth from the provider that they probably wouldn't want you to use.
It's a lot like using TiVo to subscribe to shows you want to watch vs. channel surfing with your remote control.
I like doing both.
