@estsauver while I agree that it takes some time to get into contributing into a big project like Angular 2, it is simply not true that it is "Google only" project. I'm a regular contributor (#6 in terms of no of commits: https://github.com/angular/angular/graphs/contributors) and I don't work for Google.
Angular team is bunch of great people, real pleasure to work with. I can tell you - the initial effort to start contributing pays off _very_ fast.
