Some of you may be wondering what cruel fate may have befallen our brave podcaster Jonathan Coulton out on Lunar Base One. Well, a critical Doritos shortage after a lunar cargo supply chain error left Jonathan with a choice: continue to broadcast his weekly dispatches in solitude on the moon sans Doritos, or return to Earth to devote his full energies to being the interstellar rock star that he is, with the added benefit of all the Doritos he could eat. I think we can all see how the latter option won out. We wish our contributing troubadour all the best—you can still relive all the excitement via the same RSS feed in iTunes where every episode is archived.
