What do we podcasters "think with"?

Item number 2 from Austin Kleon’s Letters mingle souls struck me…

“Something magical happens when a scientist writes with chalk on a blackboard.” Why scientists can’t quit chalk, even in the digital age. (See my post on “thinking with chalk.”)

What do we podcasters “think with”?

For me, it’s definitely not making and editing audio. It’s not chalk, of course. Maybe (?) it’s listening to podcasts…
