Podcasting is undergoing a renaissance and one podcast causing quite a stir is "Serial", the hot new creation from "This American Life" producer Sarah Koenig that takes listeners along on her journey to uncover the truth about the murder of a young woman in Baltimore and the man who went to jail for the crime.

If you're hooked on "Serial", you'll want to know as soon as the next episode is published. This Zap hooks you up with an SMS message to your phone, so you can stop checking for new episodes and maybe get some actual work done.

Enjoy!
