Hi Nir, I'm midway through the audiobook now and must say, its really fantastic. So many concepts packed into a relatively short listen. This will probably be something I have to play through a couple of times to even catch a first pass at everything. My first question is a more technical one, though. The book makes mention to a couple figures. They are described by the narrator, but I was wondering if these were available to audiobook listeners online somewhere. I purchased the book through Audible and got access to your great pack of Extras, too. More on-topic with the content of the book... Do you think that when forming habits (new service or new users) the synthesized triggers should be purely transactional, or are "digest" newsletters effective as well? By transactional, I mean push notifications, comment reply notifications, and other things that are generated by a user's preferences, connections, etc. Thanks again for the great resource. Looking forward to continuing the audio book and leveraging the techniques you mention for years to come.
