Kind of a meta comment, it's always interesting to see / hear that when a somewhat well-known author writes a new book, you see interviews with them cropping up on "all the usual" places, other outlets write about it etc.

It's nice with something like "What if? 2", because Randall is an interesting podcast guest, and there are just so many different things to talk about.

It's a bit more annoying in other cases, where within two month you hear the same author on 5 different podcasts, and the author says the same thing on each of them. Time to use the skip button.

I guess that's simply how it works nowadays in publishing: writing the book is work, but then you also need to spend quite some time promoting it, in the hopes not only that it boosts sales, but also that the boosted sales put the book in some bestseller lists, boosting sales even further.
