What are some other general link aggregators aside from HN?

It's not like those you list as there's no voting, but I maintain https://engineeringblogs.xyz/ which is a river of links to posts on over 500 software engineering related blogs. There's an OPML file if you want to take the feeds into your own reader or you can submit feeds to add.

Oh, I also run https://rubyflow.com/ which is a MetaFilter-style linklog for the Ruby community, and somehow gets a fair few posts each day.

http://lemmy.ml is a federated libre source link aggegator built on Rust ( https://github.com/LemmyNet/lemmy )

A couple venerable pillars:

https://news.slashdot.org https://boingboing.net

https://unfeeder.com/ is pretty good.

A classic... https://www.fark.com/

http://popurls.com

https://devurls.com/ https://techurls.com/ https://sciurls.com/

(and others from the Browserling folks)

Arts and Letters Daily is a nice curated list if you are looking for something a little more arts focused: https://www.aldaily.com/

I didn't know http://www.kuro5hin.org/ wasn't around anymore.

Pouring out a sip of my iced coffee for some old memories...

https://pinboard.in/recent/

https://pinboard.in/popular/

https://www.producthunt.com/

If you want shipping news: https://www.shipshipship.uk/

https://news.python.sc for Python stuff

https://www.fark.com/ still has snarky headlines and offbeat content but the selection of articles is quite varied, and the comment section still has quality content. Certainly better comments than the WSJ troll-fest.

https://sqwok.im is a topical aggregator with chatrooms built into every post.

Think of it like Twitter but with chat rooms instead async comments.

There's no voting and the focus is on science, tech, engineering, markets, hobbies, and culture.

It had a big HN post:

https://news.ycombinator.com/item?id=27629543

marginalrevolution.com has daily curated links that are IMO, generally high-quality

i like hackaday.io but maybe thats too specific

This is only adjacent to what you've asked for, but I wrote an RSS aggregator with an HN-like UI awhile back.

https://www.evalrss.com/

For ML/AI related feed: https://www.sciencewiki.com/

https://blogboard.io/ - Engineering blogs by top tech companies

https://embit.ca is a tech news aggregator with unique tag cloud.

https://icebergcharts.com, at least the linked ones

https://www.metafilter.com/ has been operating as a super high-quality community link blog for over 22 years now!

https://feed.rekt.news/

https://techmeme.com/

Soylentnews.org is a friendlier version of slashdot.

old school but still some of the best

https://www.metafilter.com/

lobste.rs, freepo.st

On the other hand, why does this question is asked so often? I see it once a month, probably.

Lobste.rs isn't a general link aggregator, anything not related to computing gets booted quickly: https://lobste.rs/moderations
