The book is appropriately comprehensive, covering the basics as well
as interesting and important applications of Bayesian methods.
Generally, the book's coverage is accurate. Because the style of the
book is somewhat informal, sometimes there is some lack of precision
(but nothing serious).
The approach is currently very relevant. It uses Python code
throughout. I expect Python to continue to be of interest in the
near and probably medium-term future, so the longevity of the book
should be quite good.
The writing style is somewhat informal, and so clarity will be high
for newbies. For those wanting a more formal treatment, it would be
better to look for a more advanced, mathematical treatment.
The entire book is written by a single author, using consistent
style, terminology, and approach throughout.
After getting the basics down, it should be easy for the reader to
read individual chapters and get the key ideas without needing to
refer much to other chapters.
The organization and flow is excellent. I found it very easy to read
the book cover to cover.
The interface is pleasant and easy to navigate. The Python code
scattered throughout the book is also easy to identify and follow.
I did not find any significant grammatical issues.
There are no particular cultural issues that I could see.

About the Book
Think Bayes is an introduction to Bayesian statistics using computational methods.
The premise of this book, and the other books in the Think X series, is that if you know how to program, you can use that skill to learn other topics.
Most books on Bayesian statistics use mathematical notation and present ideas in terms of mathematical concepts like calculus. This book uses Python code instead of math, and discrete approximations instead of continuous mathematics. As a result, what would be an integral in a math book becomes a summation, and most operations on probability distributions are simple loops.
I think this presentation is easier to understand, at least for people with programming skills. It is also more general, because when we make modeling decisions, we can choose the most appropriate model without worrying too much about whether the model lends itself to conventional analysis. Also, it provides a smooth development path from simple examples to real-world problems.
