As ever a useful analysis, however what may I ask is it that you do at Google of relevance to armchair generalizing like this, that causes you to disclose your employment every time you post? It seems to me it detracts from the merit of otherwise consistently excellent write ups, and almost encourages suspicion of bias.
I feel it's always better to disclose any potential biases or conflicts of interest up front. Cletus could have appended it to the end of his comment, but many readers might TLDR and miss it.
