Lemmy is great in the techy/gaming, memes, and news/politics fields, but doesn’t have strong secondary communities. I no longer have a reddit account but still lurk to keep up with news focused in Ukraine, Japan, Korea, music, history, minecraft, etc.

Also, social media uses the same tactics as casinos to keep people hooked. I remember a podcast in which they compared the new algorithms to slot machines where sometimes you “win” by getting content you’re looking for, sometimes you lose by getting fed random crap you didn’t search, and mostly you break even & get fed the same repetitive crap (this makes the times you “win” seam more rewarding.) Social media is an addiction and cancerous to modern society.
