Thanks for the list. I disagree with the notion that Scala is one of the biggest three scripting languages around. Judging by the startup job listings at http://www.quora.com/Which-startups-are-hiring-in-the-San-Fr... almost everyone uses Python, Ruby, or PHP. There was little to no mention of Java (in a web context) or Java-related languages such as Scala. Things might be different in Brazil, though.
