I didn't mean in terms of numbers. Of course more people use Google, but lets not underestimate the impact Github has had and will continue to have. If you're a developer, Github has essentially become a requirement to have, it's a developers resume. If it weren't for Github the numerous open source contributions I've made as well as projects I've open sourced myself wouldn't have come to fruition, and while my contributions are small in the greater scheme of things, you never know, one commit might make all the difference between a good web application and a great web application.
