Thanks for the feedback. Because of the way HN works, it supports a "nonlinear comment development process". You jot some random ideas into a comment, which can often turn into a good comment after several edits (in which those ideas no longer appear at all). Or not: it gets deleted before it is seen: there is a configurable delay before your comment goes public. I was sure that one wasn't going to be (in any shape), but I had to respond to some urgent things. That's it.
