My personal answer is kinda more of the Ask HN and Show HN discussion type content. I like those threads!

Another answer from someone else was they're hoping a discord would be less intimidating to join the convo, some early feedback before Show HN posts, and "body doubling" a la ADHD / "work buddy" type things.

Inspired by this thread - https://news.ycombinator.com/item?id=37233435. Someone asked about if there was a HN discord and I set one up and a group of 11 people joined in the past hour or so, nothing major yet but there's been a couple interesting messages.
