The significant change to GitHub announced today by CEO Nat Friedman might be the first major change since Microsoft bought the company last year: free accounts can now create private repositories.

GitHub has become the home for a huge number of open-source projects. Some of these are major, widely used projects such as the Node.js server-side JavaScript platform, but many of them are small, personal projects, half-written programs, and experiments. These projects are typically open-source not because their authors have any particular desire to share them with the world but because GitHub gave them no choice: free GitHub accounts could only create public repositories.
