Unfortunately this new thread was posted while I was asleep, and so I haven't been online to answer questions as the thread developed. Whereas in the previous thread I participated from the start.
Pro tip to anyone whose stuff gets posted on HN: It is a completely different place when the author is present.
If you're present, then the people who are inclined to post cheap criticisms shy away, and the people who want to ask questions and learn show up.
(Aside from the house, I've had my work at Cloudflare posted many times, and seen this pattern in those posts.)
