GitHub recently released the results of its 2017 Open Source Survey. The survey is an open data project conducted by GitHub and its collaborators. It was designed to gather data on open source software development practices and communities. Information was gathered about the attitudes, experiences, and backgrounds of those who use, build, and maintain open source software.
The survey discovered that the open source community highly values project documentation (which nevertheless is frequently overlooked), experiences infrequent but highly visible negative interactions, and does not reflect, demographically, the wide usage of open source software around the world.
