Ask HN: Sites with the quality of Hacker News, but for more general topics?

I've found Reddit posts and comments tend to appeal toward the average person. It's like I'm listening to pop music while reading Reddit comments - the same thing over and over again. The same kind of averageness that gets tiring and unfulfilling to read.

What I like about Hacker News is the comment and link quality is very high. What I like about Reddit is I can read about any topic I want.

Is there something that combines the two?

If there isn't something like that - maybe we should build it?

The pre-acquisition version of digg.com had many similar characteristics. The current version, sadly, does not.

https://www.lesswrong.com/, still tech focused but there are broader topics discussed. Also great for longform pieces.
