Status of Projects Using Github Data Microsoft (MS) and Outside MS contributions depend on the stage of the project. (Analyzing Github Commit Data) Non-MS contributions are lower but MS contributors working hard to build the community. MS and Non-MS contributions are almost equal MS contributions reducing but community taking over *Sqrt scale helps better visualize the skewed data July 22, 2012 Footer text here
