If I click the link you provided, my browser takes me to Lenny.ml. There I am not logged in and my credentials from feddit.de are not working. So I cannot post there.

I think it only works if the link points to a community on another instance. Like !memes@lemmy.ml . Maybe this is the intended behavior.

The downside is, you can not visit an instance and view the local communities and their post and interact with them. This makes it a lot more attractive to join the instance where the communities are you want to frequent.

Edit: the link to the community does not work either for me. But I am kind of sure, that there are links that work as intended and make you just view the community from your own insurance…

This is something I also find strange. If I click a link to an instance, I want to view their content and not visit their homepage, where I am not logged in and cannot do anything.

Yeah, the design of the individual posts in the feed is nice. Are you using kbin on desktop? Because on mobile I only get the random feeds, when I search. And at least so far I find it a little confusing, where the random stuff starts and the search results end. But I think that will get better over time.

So far I am only using Lemmy, but maybe this is also a nice entry point for the other services.

What are the differences concerning privacy, you are talking about? Aren’t they using the same Lemmy infrastructure?
