Thank you for your 10th contribution to HN in a decade. I'm happy I was able to motivate you to participate, please do it more often.

Well it depends if commenting on HN is considered "within the envelope", maybe it's not real progress worth spending time on :)

That's a fact.

Legitimately true. This is a forum for entertainment and reposting content, not really learning anything seriously.
