So this is a bit of self-promotion, but I can’t think of a better way to link all of them in a neat way: Almost all the channels I recommend (excluding some that are on instances that did not allow mine to follow them, which makes the channel cards not load properly, sadly) are on the landing/home page of my instance, in no particular order:

Follow this link for the overview! - of course you can interact and follow from other instances (including other services like Mastodon). Lemmy does not work properly for following PeerTube channels in my experience, though - don’t know about Piefed and mbin.

You can find a similar collection of channels on the landing page of peertube.wtf as well as a collection in a sticke post on [email protected]. too.
