I love how Carlin paywalls his old shows but then mentions in the podcast that they're easy to find on pirate sites if you can't afford to pay him. The paywall is thus implicitly recognised as a minor nuisance meant to make you consider donating. His is the only podcast I've ever given money to, and while I'd like to believe that this has more to do with supporting his quality content than the minor nuisance of pirating his old shows it was actually the act of looking for an old show and finding it paywalled that made me stop and punch in my credit card number. I had intended to support him for a while before that, but never taken the time.

Edit: removed "ad-free" as a descriptor of Carlin's shows, since I recall him having Audible ads.

Glad to see there are people on HN who are going out there and propagating the formula.

I haven't heard of No Agenda in years.

I stopped listening to them a while back after they had a hard right turn IIRC. Their business model was excellent though.
