HN is very slow in my eyes. The front page stays quite the same and the news is more targeted to technical people.
Is there also gibberisch and pure marketing? Yes. But that will always be on an open-platform.
Reddit was the same at the start but has now become "slower tiktok" where I even get the feeling 80% of the comments are placed by bots, marketeers,... Even my local subreddits became pure thrash.
To me HN and Twitter hit that sweet spot of productive procrastination, where I feel like I'm keeping up with the tech world and learning new things, while in reality most of the things I read here aren't valuable and it's just another way to procrastinate
