I have self diagnoised myself as having PDS (podcast distraction syndrome). The primary clue that you might have it:

• you try to wear head-phones on during dinner;
• you actually setup your laptop in your car to listen to podcasts because you don’t have a audio in on your car stereo yet;
• if you are doing a podcast, the concept of 20-GB bandwidth in a month is no longer un-imaginable; and
• you set iPodder to check for new content every minute.

There are probably other symptons but I gotta listen to the Daily Source Code (DSC).
