Other Hacker News-like link sites

I searched for HackerNews alternatives on the web once and a couple came up, but most aren’t even that good (Lobsters being an exception). Note that you need invitation for many of them.

https://mln.dev/ for machine learning

The only one I know of is Lobsters [1] Links are often cross-posted between that site and this one.
