Thanks for the comment. Actually, PHP, I don't want. For several reasons: I want to teach concepts used in real world situations such as test driven development, object oriented programming, MVC, etc... and for all of these reasons, PHP is not a strong candidate. I know there are more jobs opportunities for Java, PHP, .NET, etc... but my goal is also not to produce corporate drones but passionate people :-)
