Note: sorry about some of the noise in the audio. We’re still figuring out how to make the best of our limited recording equipment. If you’d like to help out with that, feel free to contribute to the “buy Matt and Matt some better microphones” fund via the Donate button we just added in the sidebar. And donations or not, we promise the next episode will be less noisy!
