The link to https://browse.feddit.de/ is dead and should be updated to https://lemmyverse.net/communities.
Personally i think it would even make sense to link this from the main site sidebar. Not because it is a problem finding communities on other instances from within world, at least this should be the best instance to be able to, but as a function of being a “role model” for other instances.
FYI we updated it to point to our support page copy of it, other stuff there too, bit it’s a bit of a WIP 💓
Nice!
