Lots of good advices about processes and organizations. It's nicely points out that friction is not necessarily wrong... if you get something out of it.
Also neat reminder in there that code review are here to complete work which is already socialized somehow. If you can't find reviewers it's a sign of an organizational problem when the work started.

A good reminder that there is not a one size fits all solution in the tech world. Also be skeptical of the silver bullets that "obviously" everyone should use. Project context matters above all.
