And yet... is it? Realtime means real discussion, and opportunity to align ever so slightly on a common standard (which we should write down!), and an opportunity to share tacit knowledge.

It also increases the coverage area of code that each developer is at least somewhat familiar with.

On a side note, I would love if the default was for these code reviews to be recorded. That way 2 years later when I am asked to modify some module that no one has touched in that span, I could at least watch the code review and gleem something about how/why this was architect-ed the way it was.
