isn't a lot of touhou stuff on peertube, I've noticed, but the real problem with any of these services is lack of enough content

I would suggest that before even getting more content, that it's more important to surface the relevant content that exists better. It's vastly easier and encourages new creators more as they see more viewcounts and engagement.

Currently if you search for PineTime on SepiaSearch, most of the videos don't even mention Pinetime anywhere. Mastodon's search works better... as long as you know to paste URL's of any content from unknown instances in your local instance search to bring it up for easy commenting / following. These issues make it feel like there's much less content on the fediverse than there actually is.
