It's funny to me how many big flare-ups and popular issues have been about defederating or controlling other instances but we've not really had a single popular event where users work on anything together to benefit community.
Individuals have made tools but there's not been calls to action and mass cooperation events for anything beside silencing unpopular groups. No community design discussions devising and implementing tools or features, no group efforts to catalog or document or display useful data...
I don't know if it's just that people here haven't considered the possibility of doing something positive or that outrage about others is just so much more compelling
