Actually, that's not what he said. Here's the full quote: "I’m at the end of the first chapter that explains how Erlang’s concurrency features work"

A quick look shows that it's the sixth chapter. Either way, he's clear about this disclaimer, and his post was enough to peak my interest in this specific book.

For you, first impressions _do_ seem to mean much.

That was also the first chapter in the book where suddenly Erlang seemed freaking amazing. Up until then, it was just a functional language with an odd syntax. After the introduction to message passing and concurrency, I was in love.

It's called "First thoughts on Erlang" for a reason.

Indeed. If anything, the programming landscape already has way too many inaccurate first impressions getting in the way of real discussion.
