As another commenter pointed out, you can recompile the .less files, excluding what you don't need. You can also use the web customizer in our hosted docs at getbootstrap.com.
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.
Yeah, sorry about those changes in the RCs. Really we used the wrong label and are sorry about that. All in all though, everything with those pre-releases worked out really well. Just a naming thing :).
Naming changes were for consistency across the framework.
We only use `!important` on utilities where specificity would make them impractical. Quick floats, toggling by viewport size, etc make it necessary unfortunately. When it comes to every other component though, we don't use it at all.
Major version release enable us to break backward compatibility. Other motivations aside, I see no reason to not do it in attempts to do something better.
True, we could be louder about that. I'll get a tweet out about it shortly. To be honest I totally forgot about even mentioning it anywhere but in a few @ replies and issues on GitHub.
Yeah we probably should have called them betas, but I'm fine with using RC—beta sounds way less serious and we want folks to just go to town on this. It's helped a lot.
Actually it is—it might behave perfectly right now, but the intent is that it is mobile-first and responsive like nearly every other component. If you're running into problems, let us know though via issues. <3
The purple space background was designed by an illustrator here at GitHub and I just put it to use. That the page ended up being purple and blue like Bootstrap is kind of just a coincidence. Previously the Enterprise site's background was a custom-made OS X ish space background—lots of blue and gold.
Beyond that I don't see a huge concern of the two looking similar. Bootstrap 3's homepage will be massively different from v2s today if it helps though.
I wrote all the styles for Bootstrap and refactored GitHub's forms and buttons a few months ago for a similar approach. Not 100% the same, but definitely close. All those styles are tested thoroughly within Bootstrap and made it super easy to update and standardize our styles, while at the same time dropping mad duplicate code.
The overall homepage though I think looks nothing like Bootstrap's docs, if that's what you're implying. Also, Bootstrap, and GitHub, was not influenced by Dropbox. We just iterated on that stuff internally in a pull request and shipped when we were happy with it.
All mobile first means is that instead of scaling CSS down for smaller devices, we start from there and work our way up instead. So far it's smarter defaults, little bit less code, etc.
