It would be nice to know how many people download MediaWiki via tarball or git, and how the numbers changed over time.
This does not really say much about MediaWiki //usage// (many downloads would be automated one-time things like continuous integration builds, and many MediaWiki installs are created via some third-party provider (e.g. [[https://www.turnkeylinux.org/mediawiki|TurnKey]]) and do not involve getting MediaWiki from our servers, but having the numbers would be interesting nevertheless.
Some things to look at:
* releases.wikimedia.org downloads (used since 2014 as canonical download location for releases)
* sourceforge.net and download.wikimedia.org (used to be the canonical download locations for releases in the past) - SourceForge peak download rate was 60-70K per month in 2007 ([[https://sourceforge.net/projects/wikipedia/files/stats/timeline?dates=2003-01-01+to+2010-01-01|stats]])
* gerrit clones (canonical location for master / developer setups)
* ExtensionDistributor downloads (canonical location for extensions) - ~15K core and ~15K extensions and skins a month (as of early 2018)
([[https://grafana.wikimedia.org/dashboard/db/extension-distributor-downloads?orgId=1&from=20161101&to=now&var-release=All&var-groupby=1M|dashboard]])
* Github tarball downloads (canonical location for master branch of extensions)
* Github clones (not really exposed, except on Github)
* phabricator clones
* [[https://gerrit.wikimedia.org/r/plugins/gitiles/?format=HTML|gitiles]] clones/tarballs (new thing we use with gerrit)
* old thing we used with gerrit, whatever that was
(or just assume that most of those are barely used, which is probably the case)
