My thoughts regarding Python and Perl is two fold:
#1. In my experience, many Windows developers are not exposed to "alternative" languages and tend to only consider C, C++ or
Java as a solution.
#2. While Python and Perl certainly can be installed on Windows, they are almost always installed by default on Linux distributions. While this doesn't make them "Linux languages", it does tend to mean they are very popular on Linux. In fact, many of the software packages that are installed by default on Linux distributions include python and perl programs.
Regarding Git: I have discovered that Windows developers tend to use propriety, Windows-only tools and I wanted to introduce an Open Source alternative (which can run on Windows just fine, of course).
Thank you,
