That, and so much more. I also really like seeing posts with additional context given. Like having the community side-bar visible from every post rather than solely from the community page, and the instance messages. For the sake of posterity in case anyone reads in the future, the one for Beehaw being:

This post is hosted on beehaw.org which has higher standards of behaviour than most places. Be nice.

Which gives the link to their own chosen exact wording to describe themselves.

Bc sometimes a message like:

A community of privacy and FOSS enthusiasts, run by Lemmy’s developers

Followed by a broken link, does not come anywhere close to describing what an instance chooses to be about, in terms of their admin and modding practices!:-(
