AFAIK, Peertube uses ActivityPub as well, but are Lemmy instances federated with them? I don't seem to see Peertube instances on my feed. It be cool to see Lemmy comments appear below Peertube videos.
Noting this doesn't appear to work for kbin.social - you can find the community (magazine) and subscribe, but it doesn't appear to be bringing in any content aside from some comments in the Microblog section... might be a federation issue.
I'll still try it with Jerboa, but it worked really well through the default UI (accessing your instance directly through the browser, as in feddit.nl/c/techlore@neat.tube for example)
It's usually that you were the first to try to access the channel from your instance. So your instance has to federate with the other instance, which can take a while to fully take place (and I think that it only tries to get pre-federation content on request). I think that if you tried again, you should now see some content.
Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !metastatistical@lemmy.film
