I'm primarily a Php developer. Once in a while, like to develop stand-alone script and either sell them, or turn them over to the public as open source. I've recently been use ruby on rails quite a bit, as well as some python (Django).
My question is, does the average script user care what language a script is written in? Obviously their webhost needs to support the language. But the real issue is, does the language determine whether or not the user will buy/download and install the script?
