Consider yourself patronized! Could you give a bit more info about the patrons-only podcast? Will they be about the length of a normal episode? Will you be committing to releasing them at specific dates, or just some time within each quarter? Will they mean no more general Q&A shows?
I'll admit that at $120/year, or $60 more than the previous level, for four extra podcasts, that level feels a bit expensive. (My points of comparison here are Savage Lovecast, which is $36/year for an extra half-hour or so of content each week, and We Have Concerns, where all patrons get access to occasional extra episodes.) Not that you guys don't deserve the money, but, y'know, freelance writer married to another freelance writer = not rolling in dough. But, I'm happy to give 3MA some money no matter what.
