Sorry, can't recommend a good book. My opinions come from interacting with actual product people, and from watching "undercooked", "overpriced", "poorly made", "easy to replicate" things achieve enviable success and wide adoption very quickly: PHP, Docker, Heroku, Dropbox, etc. They all completely removed friction in some narrow but important areas, and this was more important than all their very real shortcomings.
