What “notecard” means

Wikipedia

An index card, called a record card in British English and a system card in Australian English, consists of card stock cut to a standard size, used for recording and storing small amounts of discrete data. A collection of such cards either serves as, or aids the creation of, an index for expedited lookup of information. This system is said to have been invented by Carl Linnaeus, around 1760.

every network with a public tag surface

Follow #notecard 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/notecard
