The problem isn't picking up a language, it's language support (and 3rd party libraries) that are crucial. For example, if a client requests that I add a module to my application to fetch records from AD and cross reference with data pulled from salesforce, am I going to have to write a ton of low level networking code by hand or will it be trivial to find a robust open source module that does all of that for me?
