Now at the risk of getting downvoted, my experience is that Reddit is awful: spiteful posts, tons of short sentence replies that litter the eyes, circular meme-like self-referential wink-wink behavior (i.e. repeating the same joke with slight modification).
There are some thoughtful subs (star something codex) but overall it has a culture of people who write well but their reasoning stinks. They have strong opinions and make assertions speculatively. I can't read any real estate investment, market or nerdy thread on Reddit without encountering armchair bullshitisms from people who happen to write well but don't research anything, and respond with hostility when questioned.
So maybe this is my way of saying, don't change HN too much.
