  Open Source (Almost) Everything

When Chris and I first started working on GitHub in late 2007, we split the work into two parts. Chris worked on the Rails app and I worked on Grit, the first ever Git bindings for Ruby. After six months of development, Grit had become complete enough to power GitHub during our public launch of the site and we were faced with an interesting question:Should we open source Grit or keep it proprietary?Keeping it private would provide a higher hurdle for competing Ruby-based Git hosting sites, givin...
