That's only with GitHub. There are other platforms, obviously less popular, which don't take that approach.
Heck, most of the "real" free software world (the one building entire operating systems, desktop environments, programming languages, games... other than Linus with Linux) operate in that manner.
I am always perplexed when people ask me about my GitHub account for my opensource contributions: I point them at whatever the latest incarnation of ohloh (OpenHub) is where they can find thousands of my commits over hundreds of projects.
Any platforms emphasizing rendezvous? Like... Let me know whenever someone on my <fun people list> commits a new project, or is looking for help. Any meet-and-hacks later today, anywhere on the planet, which welcome virtuals? Happy to do 20 minutes of pair programming now - you know my profile - is anyone around? Text me whenever a flash-mob hackathon gets going. Notify me whenever code, any language, seeks help with <expertise domain>. Using my profile-3, find me a couple of candidate tickets for later. ... Sort of AI-facilitated social networking for humans and code.
