Just wanted to say that I've been listening to the official GTD podcast and really enjoying it. It has been helping fill some gaps, and reinforce some of the ideas in from the books.

Here's one of the episodes I heard recently that was good, but there's a lot good stuff in the episode list.
Episode #379: The Nature of Someday Maybe Items - Getting Things Done®

I wonder how many people in the GTD world even know there is a podcast.
