This article, like many on Slashdot sparked quite a religious debate over programming languages. Personally I like Java/J2EE with Cocoon up front or JSP if more people need to be familiar with the language. PHP appears to work just as well but the case can be made for almost any language available. Nothing is perfect for every situation kid. There's always classic computer science tradeoffs.
It's too bad Java has threading problems on FreeBSD according to Radwin's presentation. It's seems as if that was their only reason to not use Java.
