mdn/content now has 2000+ contributors, has ~190+ active contributors a month, gaining ~130+ new contributors a month

The number of contributors who’ve had a PR merged into the mdn/content repo has now exceeded 2000.

To put that number into perspective: As far as I’ve been able to discern, there are in all of GitHub less than 30 repos who have more than 2000 contributors. Here’s the list:

Repo	Total contributors	Uniq contributors per month (average)	New contributors per month (average)
torvalds/linux	24,000+	~1100	~120
MicrosoftDocs/azure-docs	12,000+	~850	~160
Homebrew/homebrew-core	11,000+	~225	~60
Homebrew/homebrew-cask	8,600+	~275	~70
ansible/ansible	6,000+	~30	~10
rails/rails	5,400+	~65	~25
freeCodeCamp/freeCodeCamp	4,700+	~35	~15
rust-lang/rust	4,300+	~180	~40
gatsbyjs/gatsby	4,000+	~40	~15
kubernetes/kubernetes	3,900+	~120	~25

mui/material-ui	2,600+	~50	~25

django/django	2,500+	~35	~15
moby/moby	2,300+	~10	~5
apache/airflow	2,300+	~90	~45
vercel/next.js	2,100+	~80	~50
mdn/content	2,000+	~190	~130

But along with having a high number of contributors, there’s the following:

• mdn/content has an exceptionally high number of new contributors coming in each month: over the last 6 months, we have been gaining an average of about 130 new contributors each month
• mdn/content has an exceptionally high number of contributors contributing PRs each month: over the last 6 months, about 190 active contributors each month

The rate at which mdn/content is gaining new contributors is almost unique — In all of GitHub I’ve so far found only one other repo that’s gaining new contributors at a higher rate: the MicrosoftDocs/azure-docs repo.

But the number of people that mdn/content has actively contributing PRs in any given month is also highly exceptional — In all of GitHub, among the set of repos with 2000+ contributors, there are only 10 repos with more than 150 active contributors per month, and only 5 repos with more active monthly contributors than mdn/content: the linux kernel repo, MicrosoftDocs/azure-docs, the homebrew-core and homebrew-cask repos, and the pytorch repo.
