WDW Today is all about current Walt Disney World information.  It's a podcast, but you can also listen to their episodes on your computer if you don’t have an iPod or MP3 player.  The people who record the podcasts are very knowledgeable about WDW, as they run other WDW websites, write for WDW travel books, or plan tours.  New episodes air on Mondays, Wednesdays and Fridays.  They answer listener questions on Wednesdays, and give their own advice and opinions on Mondays and Fridays.  Their website lists the notes from each episode, so you can see what they covered.  Older episodes are available to download anytime.  There is also a live call-in show once a month.  It's a great source for specific information to use in planning your trip.
