Query: Good read, but Kindle version has problems

I haven't seen the paper version, but the Kindle version seems to be missing hundreds of commas, all of them from introductory elements of sentences. I constantly found myself rereading sentences two or three times to figure out what was meant due to the missing punctuation. Other than that annoyance, this was a very good read.
