I find this chart surprising in several ways (data from ohloh):
1) I didn’t expect to see Microsoft celebrating Emacs, Linux, Git and Java
2) The chart shows C# dating back to 1997. Surely that must be including J# or J++? C# was first released in 2002, according to wikipedia.
3) 2002? Wow, I didn’t realize C#’s 1.0 release was that long ago already.
4) Emacs LISP was a huge fraction of open source in ’93? Surely that’s an artifact of the definition of “open source”
5) In my opinion, HTML doesn’t count as code. It’s data.
