Legend

Rising popularity

Falling popularity

  • Some lines skip years.
  • Technologies with only one year of data are not shown.
  • Velocity formula = (most recent opinion - oldest opinion) + (most recent usage) - (oldest usage)
  • A positive velocity means the usage and/or positive opinions have increased over time.

Retention vs Usage

This chart shows each technology's retention ratio over its total user count. It can be divided into four quadrants:

  • 1: Low usage, high retention. Technologies worth keeping an eye on.

  • 2: High usage, high retention. Safe technologies to adopt.

  • 3: Low usage, low retention. Technologies that are harder to recommend currently.

  • 4: High usage, low retention. Reassess these technologies if you're currently using them.
