@lritter I share this because I just found it and figure you might find it useful or interesting, and not in any way a defense of peertube (a thing I am largely unfamiliar with)
I just discovered that you can hit search on the peer tube "browse content" search engine with no query and it gives you Content (presumably to Browse), the quality of which seems to be reasonably above the baseline of the logged-out youtube front page
