Regarding the last point: it’s more of a bias, tho, so reducing it may even be a good thing. E.g. asking Kent Overstreet’s opinion on your bcachefs setup is probably useful, while getting relationship advice from him is ill-advised.
Advice being right or wrong isn’t necessarily the big issue for online communities (unless most other users are also wrong). What really degrades them is users acting like assholes, and someone who acts like that in a tech community is fairly likely to also do that in a political or relationship community.
