GitHub has probably been more successful than any platform at connecting developers, but I think it is ultimately subject to the same limitation as the big social media platforms in that regard: if you are connected with everyone, you aren't really connected with anyone. When someone creates an issue or pull request on your repo, you have no idea about their competence or their intentions. You have no idea if they are trying to sneak in malicious code, or if they are trolling you, or are going to get offended if you suggest changes to their PR, or if they will have the capacity to understand your detailed technical response to their query. In a word, there is no trust. So if it's a side project (maybe one of many) it's often easier to just ignore contributions and treat GitHub as a way to publicly host your code on a "take it or leave it" basis. For true collaboration, maybe other, smaller forges where developers are more likely to have something in common would be more useful.
