I write and speak lots about Kafka, and get a fair few questions from this. The most common question is actually nothing to do with Kafka, but instead:

I wrote about this originally last year but since then have evolved my approach. I’ve now pretty much ditched Paper, in favour of Concepts. It was recommended to me after I published the previous post.

I still use the Apple Pencil + iPad, but Concepts is vector-based, supports layers, grids, guidelines…is generally more powerful. Concepts is definitely worth the cost (and learning curve). It doesn’t have quite the same 'hand drawn' feel to it, but it’s close enough for what I want whilst not spending my life re-drawing bitmaps for every permutation of a diagram’s lifecycle :)
