I read the MEAP-version of it, so there is going to be a follow up of my recension here for sure.
For me the chapters are well structured, the examples easy to understand and the lessons easy to apply. I especially like that this isn't one big example, but several ones that might be connected somehow. Maybe you can benchmark the link shortener with hit?
I think the further exercises should be added to the previous chapters as well and maybe the complete list of the functions of a package isn't a bit noisy though.
