You are very much appreciated, for your well-informed comments on this topic and many others on HN. Most HN readers don't reply to comments they appreciate, only the ones they disagree with. And many don't understand about upvoting, or don't bother.

Just to add my thanks too! Especially the point about control tasks - brought a new perspective for me.

You are one of the commenters here who I am on the lookout for. You always have something insightful to say.
