skeptical of a platform's claimed monthly (or daily) actives? here's the same napkin-math exercise from the sankey's perspective of posting, not headline user counts: estimated posts/month, and posts per actually-posting user per month, in 2026. Illustrative napkin-math, not sourced analytics — the posting bases here are this page's own estimate of who's actually active, not any platform's self-reported MAU/DAU.
Reading it: bars rank platforms on whichever metric is selected. "Posts / month" is total estimated post volume (millions). "Posts / user / month" divides that by this page's estimate of the actually-posting base — not the bigger claimed MAU/DAU — so X's giant volume comes from a much smaller, very active crowd, while Mastodon's tiny community posts at a much higher rate per head. Hover a bar for both numbers, or flip to the table.
