I also enjoy that sense of narrative- an example I remember from Beeminder is the topic about Triangular beeminding for alcoholic drinks.
Maybe Beeminder’s a tool applied to so many different things that there’s no nucleus to bond over? Or that there’s already a community for a topic?
For myself, I have a ‘complete to-dos’ goal for my Habitica, but I discuss those with my Habitica party. I have a Duolingo goal but I discuss it with the Duolingo Guild, also on Habitica. Sleep and fitness I have goals for, but those are through Fitbit.
Going back to my first paragraph, I’d say the current forum is meta-focused; that the community is about tool discovery, tool use and troubleshooting, and expanding current tools to new areas.
