GitHubber here. There's some great questions in this thread already. I'm AFK this weekend, but if you've got more questions about our structure, or how we use GitHub.com to work like this, ask away and I'll try to answer them in a blog post next week.

Does github use Jekyll for it's blog? And what chat/video conference software is used, Skype?

Fellow GitHubber here :).

No, we don't use Jekyll for our blog. It's part of the GitHub.com codebase I believe.

For chat, all standard stuff really :). We use Campfire for group chat (dozens of rooms), Gtalk/AIM/etc for individual chats, and Skype or FaceTime for video chats.
