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.
