If you apply a set of criteria then that is the result.
The more interesting metric (though hard to quantify) is how much is earned with software.

I would think ASP.NET/C# would make the most profits in the dynamic web language space.
My point being that CF has a license, whereas Ruby and Python do not - which has little value in gauging success, a la IIS v Apache/nginx. (Ignoring the reality of open source Railo and Open BlueDragon for the moment)
They also both have licenses, but they don't charge money to obtain a copy.
