matrix: What else than chat is Matrix being used for?

[Mikaela]

I am thinking of #acter.global:acter.global and #minestrix:carnot.cc and #cactus:cactus.chat and whatever else.

The first is organization tooling or something, second a social media and third website comments

TODO: check what Acter is about, I just remember something about Mobilizon challenger or event organizing?
