YouTube: Secular Talk, Neil Carter, The Atheist Voice (that features Hemant Mehta Friendly Atheist), The Atheist Experience
On You Tube I Like a bunch of the channels related to Hank Green and John Green, the VlogBrothers: SciShow, Sexplanations with Dr. Doe, The Brain Scoop, Crash Course. I also like The Young Turks for News (there was a Humanist Hour podcast with Cenk Uygur, who is the main TYT guy and won the AHA's Humanist Media Award a few years back, and I really liked what he had to say about the media.
