I feel the same, but it helps to not just browse “subscribed” but to also check out “local” and especially “all”

You can also take a few minutes and check out the “communities” overview and join those you recognise by name or browse a few of them to decide if you want to join them.

It does not matter on which instance most of the time. Also, I am subscribed to similar communities on different instances, cause why not. Worst case scenario: I get duplicate news.
