I'm a native German speaker and this localization thing seems like a really bad idea.
I can understand where the github folks are coming from but it really is a thing not worth putting any effort into.
I sympathize with the humanism but programming and programmer communication should be mostly pragmatic.
The open source community is a global thing and English has won a long time ago as the definitive choice for a global language. It seems like it's easy enough to pick up for a lot of people all over the world.
In my opinion it works especially well for technical writing.
Actually, as far as I can tell, it has nothing to do with "official" GitHub. It's some guy with the GitHub username "letsmake" using GitHub pages [1].
I really wish GitHub would start doing something about people using that feature to make it look like they're part of (or speaking for) GitHub. It's incredibly misleading some times.
Sites that allow users [to have significant control over] personalised subdomains are also problematic for things like NoScript and other whitelisting tools. Since I have github.com permitted, all the subdomains inherit that permission.
I'm not even sure what a good model/UI would be to selectively white/blacklist subdomains.
