I'm sorry to hear you had a bad experience from the previous (and this) hn discussion, and I really appreciate you taking the time to comment here [edit: in spite of having a bad experience -- frequently it can be tempting to just walk away, as most of these kinds of debates only ever seem to spiral downwards into a pretty dark place, no matter how many well-intentioned participants there are].

I too find it a little disturbing that comments on this second instalment seem to revolve around the introduction to the previous one -- even if I too had some comments on that[1]. As for why people comment on it, one of the reasons might be that the "Who is it for section" was quite long compared to the rest of the post (which is fine, but it isn't surprising that it then becomes the subject of discussion).

The one-line introduction on this post doesn't seem to warrant a lot of discussion, however...
