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.

That looks like a nifty and convenient tool.

Seriously this is an awesome and badly needed technology. Let's hope it spreads.
