If you're in the early stage building a product, their podcast is extremely helpful. It really deserves a Show HN all of its own.
I particularly enjoyed two recent ones, Authentic Marketing[0] and Principled Products[1] (which also has some background about 12 Factor Apps, if you remember that). Very useful for our stage where we have a new thing, but we're still trying to figure out how to explain it.
Thanks Adam, et al!
