Serial

I am always late to the party --- any party. For the past 3 days I've  been listening to the podcast "Serial".  I had heard about it, but never thought much about it, while it was trending live.

A friend (who used to have a wonderful cooking blog, Brenda's Canadian Kitchen.  Anyone remember it?) told me that I should listen to it as I walked.
Well, I liked it so much after the 1st episode I couldn't stop and had to listen to all 12 as fast as I could.  I had to play catch up.

So the question is--what other podcasts should I not miss?  

Here is what it is -- a short description from Aboutserial.org:

Serial is a podcast from the creators of This American Life, and is hosted by Sarah Koenig. Serial tells one story - a true story - over the course of an entire season. Each season, we'll follow a plot and characters wherever they take us. And we won’t know what happens at the end until we get there, not long before you get there with us. Each week we bring you the next chapter in the story, so it's important to listen to the episodes in order, starting with Episode 1.
