Most Popular Languages on GitHub
github.comStrange that 3 of the top 5 Java projects seems to be Chinese based coding notes as opposed to actual software. The only real project in the top 5 is Elasticsearch.

It's interesting that, the more stars you filter by, the higher Go climbs up the list. It eventually passes both C and C++.
Also interesting that 4 of 5 java top repos are actually books/guides while 4 of 5 Go top repos are well known/impacting projects (the golang itself, kubernetes, mobi, lantern). [edit: typos]
JavaScript, Java and HTML.
The web reigns, apparently.
