Podcast about management

I am always looking for people, books, sites, podcast that can make me a better person to work with. There are quite a few sites out there that have help for managers, but the one I found that has the most relevant and interesting information is Manager-Tools.com. It is a weekly podcast by two management consultants (Mark Horstman and Michael Auzenne) with practical advice that can used in our day to day life. Mark and Mike provide an fresh insight into business advice, management consulting and personal coaching. Highly recommend it to anyone thinking of moving into management.
