3.0

I'm not reading the hardcover edition, rather listening to it free on Spotify, but I couldn't see that option in the editions.

Anderson explains how 'free' can work to create a business model that generates revenue. For those who are accustomed to today's technology and freely available information, there isn't anything groundbreaking, however Anderson's research and history are interesting and compelling. I'm a little sceptical about the idea of rounding down very small amounts, in that they're so low value they're close to free - there seems to be a fundamental difference which Anderson himself recognises, for example the psychological convergence between receiving something free of charge and receiving something for a payment of 1 penny.

Overall, a good and thought-provoking read.
