I hope this is additive and not too much of a tangent, but the folks at 37signals (Basecamp) have a similar philosophy. A couple links below to some good articles on their philosophy. Honestly I've never worked anywhere where 1:1s and synchronous stand-ups aren't the norm, and any attempts at async stand-ups I've had have been really bad ("Slack stand-up today!"). But I'm intrigued by it.
