Neocities.org is pretty straightforward it’s a revival of Geocities. People make personal websites or sites for their weird niche interests. It has a very minor social media component where you can ‘follow’ people’s sites, and you get updates when they get edited.

Gemini is a web protocol, like HTTP, but it’s text focused, and geared towards non-corporate, hobbyist use. It has a mirror of Wikipedia, its own search engines, a BBS board, etc. To access it you’d need a special web browser. I happen to really like Lagrange

IQ is pseudoscience

And Marginalia Search for non-corporate, independent, stuff

Neocities, the Fediverse, and Gemini Protocol sites are where I spend the vast majority of my online free-time, and it’s so much more pleasant than the big corporate slop websites
