Great episode of one of my favorite shows.
Marco seems to be able to move on from more projects than most people are able to start. I really miss Build & Analyze and I believe it is among the best materials out there to learn about developing real products in the iOS platforms (which goes way beyond coding). Instapaper won't be missed at all, since it is not going anywhere, and I am positive the service will remain great since there is a very good groundwork well set and a lot of thought seems to have gone into choosing Betaworks as its new home.
Here's hoping Marco will soon bring out yet another great thing .
