I use newpipe, freetube instead of youtube.
It has everything but the discoverability that youtube provided.
I would atleast like a way to find new channels based on the channels I subscribe, if not new videos based on watched videos.
Need suggestions.
I sometimes enable the recommended videos in newpipe just to see what’s out there, it’s mostly shite, though. For me what worked was asking people. Sometimes my friends, but more often, hanging out in online communities/forums relevant to my interests gave me a bunch of good channel suggestions :)
