Tried to visit the main site, and this popped up?
https://browse.feddit.de works only for Lemmy's instances and communities, so if you want something more precise than your instance's search bar you should go to https://kbin.social/magazines and then copypaste the link to your instance (in your case feedly.j-cloud.uk ) search bar if you want to subscribe to it. In all cases, Kbin is different form Lemmy if seen from its own site, since they are trying to do a more comprehensive social platform, while instead Lemmy is just trying to be a link aggregator (The same typology of Reddit and of other now defunct sites). So, to summarise up, from lemmy you can see all the contents of kbin (which is a different software) but the "experience" is different from the one you have on the kbin site and thus, functionally, when using a lemmy instances kbin can be treated as another lemmy instance, even if it isn't.
