PeerTube's Content Wasteland
PeerTube is a video platform that offers an amazing promise: imagine a video portal like YouTube that isn't monetized, isn't curated by algorithms, doesn't censor people, and allows anybody to host it themselves. My rule of thumb here is that, since I know most of the people on the instances I'm connected to, I can scrounge around to see if anybody is announcing new instances being founded, new channels being started, and new videos being uploaded. Community groups dedicated towards PeerTube are kind of the best way to find formal announcements of instances and videos. The PeerTube project offers two entrypoints for parsing the instance list - the list itself, and the much more user-friendly Instance Picker. When it's an instance that revolves around a specific theme, most of the content seems to align to it quite nicely. If you follow another PeerTube instance as an admin, you can add that instance's video catalogue to your own, which in theory can create a more robust search index. Taken to its logical conclusion, it's also possible to automatically follow every new instance that's listed on the PeerTube Instance list.
