What “zero” means

Wiktionary · Wikipedia

zero/ˈzɪəɹəʊ/

  • nounThe numeric symbol that represents the cardinal number zero.
  • verbTo set a measuring instrument to zero; to calibrate instrument scale to valid zero.
Full entry on Wiktionary →

0 is a number representing an empty quantity. Adding 0 to any number leaves that number unchanged; in mathematical terminology, 0 is the additive identity of the integers, rational numbers, real numbers, and complex numbers, as well as other algebraic structures. Multiplying any number by 0 results in 0, and consequently dividing by 0 is generally considered to be undefined in arithmetic.

#zero across platforms

every network with a public tag surface

Follow #zero 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/zero
