I posted a couple days ago about how David Allen's book "Getting Things Done" has really changed my work-life. Now David Allen has hooked up with productivity blog/board/wiki 43 Folders to start a productivity Podcast. This sounds really interesting.
What a great idea! The basics of GTD can be laid out nicely in a book, but a lot of the most interesting stuff is bound to come in one-off questions that can be answered in a Podcast. The biggest barrier to really implementing a productivity system is consistency, and putting it in a Podcast encourages constant re-evaluation of your own progress.
