This “You Should Know” post is top of ~June, for good reason. This post announced the kbin.social Federation/compatibility with Lemmy.
A huge amount of test-posts from a wide-variety of instances came in to test the new federation abilities (including from kbin.social, one of the biggest kbin communities).
I think this post shows the hope that over the long-term, we can get federation across the larger fediverse. I don’t know if Mastodon is in the works, but these kinds of posts give hope.
Commenting from kbin; what makes it over to here seems pretty variable - sometimes I feel like the feed is all lemmy posts, other times lemmy might as well not exist.
