Sign up for newsletters from interesting people, they'll send you down more rabbit holes than you'll need. Corey Doctorow, Robert Sloan, Tim Ferriss, Kneeling Bus, Jeremy Singer-Vine, The Convivial Society, Eric Weinhoffer and Peter Attia are a few to check out.

After that and Hacker News, I suggest setting up a decentralized media account such as Scuttlebutt, Beaker Browser, or Mastodon.
