On the face of it, Lbry is a YouTube competitor based on privacy and community. You can tip creators directly, but otherwise it basically works as you'd expect, only with fewer features (no subtitles, for example). They're also proud freedom of speech advocates. Which might explain why their homepage at time of browsing included conspiracy videos, Bitcoin pyramid schemes, and men's rights activism. It does appear to have quite a few educational YouTubers (MinutePhysics and XKCD are both advertised on the home page, though searching Minute Physics got me a top hit of a conspiracy video dissecting an MP vid, above the actual channel content).
To be clear, I support any competition for huge industry juggernauts like YouTube. If that is done in an open manner that embraces the distributed web and respects user's rights, all the better. I may have been left a little cold by Lbry, but I want to keep an eye on it and hope it goes somewhere interesting (hence making the note).
