How do you see all the features of PeerTube fitting into Lemmy?

I mean, videos and text are basically just posts, right? What features couldn’t be implemented on lemmy?

All the platforms are already connected. You can follow a PeerTube channel from Mastodon. You can post in Lemmy communities from Mastodon. People on Pixelfed can follow you on Mastodon.

I haven’t seen a way to post in Lemmy communities directly from Mastodon. The bigger issue for me is that there’s no easy way to search across all these platforms. If I’m into a certain topic, I have to go hunting for it on each one separately.
