I think Peertube is the best, not immediately but in potential. Given that, I’d suggest sticking around, interacting, making contents yourself and sharing stuff from there with your friends, so the environment gets traction and so those interested in improving the engine, the environment or just doing the same you did for traction, gravitate towards.

Personally, I’d say it’s the same as people saying Lemmy wouldn’t go anywhere when Spez was going coo-coo some years ago. While Lemmy itself is more or less stagnant, it was a good kickstart then. And now, from what I saw in statistics some weeks back, comments are increasing on the “threadiverse” even if posts are slowly decreasing, which afaik is a better sign of organic growth.
