I’ve tried Lemmy a bit last night. I know Lemmy threads can be searched and browsed here and I’m not sure it matter, but if it does I hope it’s Kbin that wins the mass adoption war. I’m finding the Kbin UI experience more enjoyable. I also appreciate the way it combines a microblog tweet like feature with reddit type usage into the same platform.
I think RSS would be the best Youtube alternative. RSS works great for just about anything you want to broadcast. I don’t know why people refuse to use it for video.
