Marco Arment helped bring Tumblr into existence, founded Instapaper and The Magazine, co-hosted the podcast Build & Analyze, and created the podcasts Neutral and Accidental Tech Podcast with Casey Liss and John Siracusa. He has a lot going on, but less than when we recorded this two-part podcast weeks ago. (This is part 2.)

I didn't know it at the time, but Marco and I spoke as he was finalizing a deal to sell the majority interest in Instapaper. Go back and listen to Episode #20: So Successful That He Fired Himself (part 1) for how Tumblr and Instapaper grew.

In part 2, we talk about Marco's podcasts, The Magazine, blogging, advertising, and related topics.
