I see a lot of the members are appreciative of this. This venture may or may not take off, but I have to ask this: Why do we need another forum that will potentially split the community?
This is 'hacker' news after all. Can't this website release its forum software so that a bunch of interested volunteers (no me) could improve it? Wouldn't that be really meta and cool?
The main gripe I have with HN forum is lack of reply notification. Secondly, the crowd tends to overdo the hacker-nerd-geek thing by discussing unrelated minutae till the cows come home which inflates the comment count. This sort of discourages posters to post their POV fearing it will be buried amidst the 500+ comments. We have a visibility problem.
We just need a few tweaks.
Further, looking at all the passionate discussion about AI and ML that happens here, I am sure some of the regulars would like to implement a scheme that learns my 'collapse the chaff' pattern and spare me the gory boredom inside a thread.
(I think what I wrote might come across as snarky, but I assure you I am not being so.)
