alt Hacker NewsI don't think GitHub stars are what makes GitHub sticky. Having a single UI / account and being able to jump between work projects, private projects and random open source projects where I want to open a quick issue or submit a PR is much more sticky.
The reason why GitHub is sticky was exactly this. It’s easy to fork, make a change, and submit a PR to another project. It’s the same interface for your code vs another person’s. It’s a simple, consistent interface to submit an issue.
You can argue that the lack of diversity in infrastructure is bad, and I wouldn’t disagree. I think we should have more projects to explore better ways of working. But, the tradeoff is that when you have a centralized system, like GitHub, you also have less friction. The learning curve is small when everything uses the same tools.
