Celtic Heroes

I am a huge Podcast junkie, since i have a 45 minute commute daily. I was hoping for people to list a few in case i am missing some gems.
Here is a Personal list of 5.
1. Dan Carlin Hard Core History
2. WTF with Marc Maron
3. Major Spoilers/Critical Hit Podcast
4. Raidlab
5. Most of the Smodcast shows. 10+ podcast wrapped in one.

These are my staples, my list can go on and on if people are interested.

You should totally listen to Massively Portable, a podcast about mobile MMOs. We mention CH a few times, though much of it is about O&C.
