More of this kind of info will probably be publicly available the closer we get to some concept of a Discourse Hub. But right now we don’t have a simple way of letting people opt-in/out of such lists, which is very important seeing as not all communities will want their data open to the public.
So, better to err on the side of caution while we figure out a good way to present this data without stepping on any toes.
If you’d like, feel free to start a “Share your data” topic and invite other admins to share their stats. That could be pretty interesting, and is also quite fitting around this time when many of us are starting a new calendar year. Just try to make it about something more interesting than “who’s got the highest numbers”.
