Kbin used to try to do this. Not so sure about Mbin, maybe it does. Glad to see a Fediverse option trying to implement something other ones implemented.

Although I am curious how many people take the approach of clicking a random active user online—I know I come to these thread-based forums to discuss common interests, and would never use the feature myself because 1) no guarantee the active user has common interests 2) I would feel like a weird stalker. Curious about the mindset of those who do—and not trying to accuse them of being stalkers just because I personally would feel like one taking that approach.

Does active people equal to MAUs? Or does it use quarterly active users?

Piefed now has a built-in alternative to Lemmyverse

One of the main advantages of Lemmyverse is its accumulated knowledge of communities on remote instances which are not yet federated with one’s own instance. Does the Piefed version offer this, and if so, how?

This is a great idea. One of the toughest parts of the fediverse is the lack of good searchability options.
