This place is amazing, and I learned so much about a variety of topics. Most of my MD colleagues use Twitter or Facebook, where the signal-to-noise is much, much lower. I assume there have been plenty of spin-offs from HN (I would LOVE to have a similar forum for discussing medical issues; Can I fork the codebase somehow?), but I do think the secret sauce is moderation.

Also, politically, I'm "an enlightened centrist" lol and nearly all of the political spectrum here is represented well IMO, and even personal attacks/strawman arguments are not immediately banned but first discouraged.

Thanks dang!

dang has already mentioned the original Arc forum but I'd be remiss not to mention Anarki[0], the public fork. It's diverged quite a bit from Hacker News though so don't expect feature parity.
