You are experiencing code reviewing whenever you are writing
production code.  Do you find that it improves the code quality?

I've found that both pair programming and less-intense kinds of
reviewing are usually extremely helpful.

Yeah, that can be a problem.  That problem has made it hard to
introduce pair programming in some places I've worked; it largely
depends on the social dynamics of the place.

I mostly agree that inspection during pair programming finds the bugs
any inspection is likely to find.
