That's what I was about to say, it doesn't = matter from a technological point of view. So if the programming = language is irrelevant, but you have to pick one, you'll start looking = for arguments to prefer one over the other (based on available = libraries, marketing, etc.). Some argument made Facebook pick PHP = (instead of Perl, Java, Ruby, C/C++, OCaml, Haskell, Standard ML, = whatever), probably something trivial like availability of PHP = developers, or simply because PHP was popular at that time (i.e. there = were people who knew the term "PHP"). Now the world looks different of course, there are hundreds of millions = lines of existing code, and really porting all that code to a new = language would involve a lot of effort, money and time.
