Just reviewing what I've got added to my feed reader:
* tilde.news
* Lobsters
* Slashdot
* lemmy.sdf.org
* the linux sub on lemmy.ml
* A selection of the less annoying subreddits, like r/askphilosophy
* A selection of local news websites for where I live
* A selection of blogs written by random people who I think are interesting
* Hackaday
* indieretronews.com
* Hacker Public Radio
* HN of course
* And other random stuff. And dm.hn is probably going to be amazing when I have some time to comb through it
In the event that none of it's interesting, I pop open a Gemini client and just start clicking around, I always find the most random long ramblings. The Lagrange client in particular is a very refreshing reading/browsing experience.
Internet content has never been better and I don't feel overwhelmed by inauthentic stuff at all, I know that there's a lot of it out there, but it rarely reaches my eyeballs, mainly through the now-decaying morass that is Reddit sometimes.
Mind you it took me years to come up with the list of feeds I like and it's very personal to my interests, but it's always just been a text file that I edit so it was easy.
