I was a bit surprised that there were no questions about: where people look for documentation, where people expect to find documentation, API documentation in general, documentation format in general, nor how documentation should be maintained.
Personally what I would like to see (in the long term, not necessarily in the next six months) is a focus on systematic reference documentation. i.e. things like: every repository should have a README that clearly explains the “what” and the “why”; every API should have a description and a usage example; every setting and feature flag should have a description; every plugin/integration point should be documented with an example, and so on. Django is an example of a project that does this well.
