Heath - thanks very much for taking up on the baton on this! In the spirit of healthy debate, we hope you won't mind us offering this by way of riposte...
Is this really a review of the review? You only actually mention one of the points John made: his objection to the Rework suggestion that all meetings are toxic. To which your reponse is that meetings are pointless 99% of the time, adding: "Sure, there are rare exceptions to this rule, but it is far from an “over-heated generalization” to say that meetings are toxic." Now I suspect lots of people would disagree that 99% of meetings are pointless. But even if you're right, and just 1% are worthwhile, surely that still makes it a generalisation to say that meetings are toxic?
The rest of it just seems to be speculation about the reasons for John's business success based on what it says about him on the internet. Isn't that more of a personal hatchet job than a review of his review?!
