This is a bit off-topic, but one aspect (among many others) of HN that I really appreciate is that there aren't any snide remarks pointing out how this is a repost (I'm not suggesting that's what you're doing); no one here cares. If you've seen it before, great, perhaps you could contribute to the conversation in this current thread based off your learnings the last time around. If you haven't seen it before, here you go. I hope it always stays this way.
