I’ve just started reading this but wanted to quickly say that the preface and opening chapter (everything up to the beginning of ‘Part 1’) is not only one of the best openings of any book I’ve read, but also does one of the best jobs to sell the idea of a piece of technology - ever!!
I was going to suggest PragProg consider making it a free download - because I reckon it will do a phenomenal job of helping drive adoption of Elixir and Phoenix …which in turn will mean significantly more potential customers/readers - so a win win for everyone 
but guess what? It’s already available as a free download!! (Get the preface here and the introductory chapter here.)
Well done Chris, José, Bruce, Jacquelyn, PragProg and anyone else who made that chapter what it is 
whenever anyone now asks “Why Elixir?” I’ll definitely be including this resource and I can’t wait to read to the rest of the book!
