* Pull requests as a major dev artifact. Probably the most reliable tracker of a set of decisions at a point in time
* The connection of the issue tracker to the code base and not as a separate tool (ie Jira).
* Expectation of a basic README with the project with the basic documentation.
We take these things for granted now, but pre GitHub this was NOT the norm.
I’m not sure I frankly want a competitor here. It’s one extra annoying thing for me to think about. Opinions are good for streamlining my life as a dev.
