Yay Complice! I encourage all Beeminder users to try it. (Also I’m hanging out in the Beeminder room on Complice right now.)
For ideas 1 & 2 I feel like it should be something more structured. Maybe something like the way we do IFTTT macros so there’s no ambiguity about when you’re triggering a Beeminder update. Or even more structure where there’s an actual numeric field or something, but that’s more work to implement and adds complexity to Complice.
