Who built it
TOCW didn't put on 199 events — 201 hosts did. Companies, labs, nonprofits and neighbours organized 189 community events on their own initiative, and collaboration ran deep: 64 events were co-hosted by two or more hosts. That's not an audience; that's infrastructure the platform keeps.
