Compression
I realised I could compress my book into a medium-sized Reddit post because very little non-fiction actually survives once you remove pacing, repetition, scene-setting and the padding required to justify a spine and a price.
The real reason not to compress a book into a blog is that a book forces the reader to spend money, time, attention, and sustained effort. Most people operate on memes, vibes, slogans, and borrowed certainty and they simply will not pay that price. They drop out early, which is a feature, not a bug.
There is a straightforward trade-off here. Compression maximises reach and noise. Length sacrifices scale to preserve coherence and to avoid endless remedial debates with morons.
Complexity is not indulgence and it is not elitism; it is geo-fencing.
As it turns out, most people I know are morons. But I knew that already.
