Yeah I know. People bring up r/science and the history subreddits all the time. And you're right, they do stick to the topic. The trouble is that they're both very siloed. If you don't like those topics all the time, you have to go elsewhere. Hence my comment on signal to noise.

Totally agree about the no humour thing on HN though.

Hacker News tries to be siloed, it's just that the silo is vaguely defined and subjective ("anything that gratifies intellectual curiosity.")
