Howstuffworks
The above link brings you to the homepage for all HowStuffWorks podcasts. I listen to Stuff You Should Know most loyally, but Tech Stuff is great for updates and discussions about new technology. Stuff You Should Know provides an entertaining look at just about anything you can think of. The hosts, Josh and Chuck, are very humorous and do a great job talking about things they think we should know.
BlizzCast
This podcast revolves around games developed by Blizzard Entertainment such as StarCraft II. The podcast looks into new developments and updates and provides in-depth discussion on each Blizzard game.
Just Vocabulary
^^ Pretty self-explanatory. This podcast is short and concise. It presents a couple "cool" English words, defines them, and uses them in a sentence. It is a fairly ineffective way to learn words, but the podcast is valuable nonetheless.
This American Life
I do not listen to this podcast, but I've hear excellent reviews. Josh and Chuck joke about the podcast and its host, Ira Glass (sp?), because Stuff You Should Know is always just behind This American Life in ratings.
