Depends what you mean by “non-commercial” and “stuff”. Does community-supported via Patreon count? Are you after music, video, fiction writing, non-fiction, comics…
Stuff as in anything, intentionally broad there.
Non-commercial is harder to nail down, but by and large I mean not-for-profit, sort of casual hobbyist activity with zero interest in trying to turn it into a business/side-hustle. People discussing/sharing their original stuff simply for its own sake.
Not fan work, coverage of commercial works, etc. Nothing against that stuff, it’s just easily found and readily available.
I mean there is peertube for video content. I know my instance runs aNONradio which is pretty eclectic music and talk radio, but there are probably other similar streams. There’s quite a few services for CC licensed music. Personally I listen to a lot of actual play RPG podcasts, which are probably right on the border of hobbyist / side hustle stuff. More indie and low budget than say, critical role or the like, but still partially monetised, even if only to cover costs.
Do you mean social media?
Could be (at least fediverse style), but not sure who/what to follow or how to filter out what I mentioned.
HN and Lobsters has got me really into following blogs.
