Worth mentioning that we, as in me and @pmusaraj, were in the https://fairtechsummit.org/ and https://conference.opensource.lu/, presenting on both last week. We met so many Discourse operators, like Fairphone, KDE, Ingress, etc.
As Discourse is now part of the https://super-stack.eu/ coalition, we will most likely be at next year FOSDEM 2027 too.
