It is a pity that #Peertube has never been well integrated with #Microblogging. The primary way we become aware of a #video is when someone drops the URL in a toot, and we open it in a separate tab. We watch while not logged into the particular @peertube instance, thus not giving likes and having interesting discussions in the comments section.
Same is true for #Pixelfed and #Mobilizon etc.
While organically building my social graph for years, this stuff just doesn't reach my timeline mostly.
