Here's a few people that I find; inspirational, funny, helpful to me in some way.

Chris Hardwick and the gang at the wonderful Nerdist website.
They make podcasting fun while retaining just a hint of the narcissism.

Neil Degrasse Tyson's podcast. I only listen to two podcasts, and his is the second.

Modders-Inc.com. I have been going here for years to learn and gain inspiration from all those amazing people.

I'm sure there's me in there too. I find me fairly funny and somewhat inspirational. But rarely do I find me helpful, so I put me on the next page.
