What “hashmap” means

During lookup, the key is hashed and the resulting hash indicates where the corresponding value is stored. A map implemented by a hash tab

every network with a public tag surfaceFollow #hashmap 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.
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/hashmap
