where microblogging's active users went, 2022 → 2026 — a sankey of estimated monthly actives (millions) flowing from each site's 2022 crowd into wherever they ended up. Illustrative napkin-math, not sourced analytics — built to tell the story of the exodus/fragmentation, not to audit anyone's MAU count.

Reading it: left column is each site's estimated 2022 monthly-active crowd (plus a "not yet posting" pool of people who join a microblogging site for the first time by 2026, via Threads mostly). Right column is where that crowd is estimated to be in 2026, including a "left microblogging entirely" sink. Ribbon color = the platform the users came from. Hover a ribbon or a box for the number; tap the pill above for a plain table.
