  • Tags are sets. Many apps support tagging of content, but most of them (incl. Mastodon) treat tags only as singular/isolated topic filters, akin to a flat folder-based approach. But tagging can be so, so much more powerful when treating tags

#sets across platforms

every network with a public tag surface

Follow #sets straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.

X (Twitter) ↗Instagram ↗TikTok ↗Facebook ↗LinkedIn ↗YouTube ↗Threads ↗Bluesky ↗Mastodon ↗Reddit ↗Pinterest ↗Tumblr ↗

Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/sets
