Would this subreddit be relevant to your land management ask?
Subreddits tend to be great for niche interests, but less so for specific intersections.
Ideally, if enough people listed their interests on an anonymous platform, I could at anytime see previous discussions on any combination of interests (and also participate).
I'd be interested in something similar! Though, I'm not aware of any platform that offers this...the closest would be Reddit since it hosts the niche communities.
I’m struggling to conjure the user experience. Even whether the medium would be instant messaging or discussion boards. I learn toward the latter for the sake of posterity.
