I have long believed that whatever comes along to replace the reddit/HN etc type site will be based almost entirely on trust networks.
i.e. only surface stories posted by or upvoted by those you trust, and the inverse with those you distrust.
Then exponentially drop off trust transitively and it could be almost workable.
I sometimes feel like a paid newsletter that's curated by users would be fun. I'd happily pay €5 a month for a weekly/daily digest where the comments are en par with HN.
The risk is to build very good echo chambers. One shouldn’t have to read AI slop or despicable opinions during their free time, but some exposure to alternative respectable and not idiotic views should be part of the design.

Like Facebook/Linkedin?
The return of Advogato. If you weren't around for it, it had a certification system like what you describe, so the stuff on it was pretty good. After a while, spammers figured out that it had very high search engine placement because of its quality, and that pretty much ruined it. It's gone now.
