Followers are the odd one out among our metrics: every other number counts something a developer did, while followers count people who chose to watch. It's a measure of reach, not contribution — which is exactly why it's worth having next to the others.

What the number is

The current follower count on a user's GitHub profile — a snapshot, not a history. GitHub doesn't expose when each follow happened, so unlike commits there's no lifetime curve to draw; followers appear on the leaderboard but have no chart on profile pages. We refresh the count when a profile's data is refreshed.

How people actually get followers

Follower counts obey attention dynamics, not effort dynamics:

A hit repository converts stars into follows for years after the fact.
Teaching — courses, books, conference talks, YouTube — reliably builds followings that dwarf typical maintainer numbers.
Being early or central in an ecosystem: framework authors and core maintainers accumulate followers as a side effect of being upstream of everyone's stack traces.

The result is that followers and contribution counts are nearly independent axes. There are engineers with tens of thousands of total contributions and three hundred followers, and developer-educators with the inverse. Neither number debunks the other; together they locate someone on a builder ↔ broadcaster map.

What it doesn't measure

Skill, output, or even present activity — follower counts essentially never go down, so they encode peak visibility, including that of people who left the platform years ago. And like every social count, they compound: visible people get more visible. Treat large gaps between two people's follower counts as differences in audience, not ability.

Why we include it anyway

Because the contrast is informative. Sorting the same population of developers by followers and then by reviews produces almost comically different leaderboards — one is who you've heard of, the other is who keeps the code flowing. Having both on one site is the point.

See it in action

Open the followers leaderboard, then flip the same board to Commits or Total and watch it reshuffle — or look up someone famous and check whether their fame is builder-shaped or broadcaster-shaped.
