We don't have a specific reward for this one, but we guarantee that you'll almost definitely have better karma after supporting the podcast. (If you don't, we accept no responsibility for any bad karma associated with your donation.) 

Seems like good reasons.

Record a question (instead of emailing in) — Ben and Nathan will play, and answer your question on the podcast! 

Just record the audio file with a smartphone or computer, and send it to us!

(You'll also get the previous tier reward!)
