The purpose is to satisfy extra-curious readers (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&query=by%3Adang%20extra%20curious&sort=byDate&type=comment https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...) who might want to read previous discussions of the same story. No criticism is intended! I add this because sometimes people think there's an implied "why did you repost this, it's already been discussed" - but not at all: reposts on HN are fine after about a year or so: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&query=by%3Adang%20reposts%20year&sort=byDate&type=comment https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que... * than you could possibly want, but oh well
