IMNSHO, Java has to be the absolute worst language out there. Total system resource pig. For example, certain web sites I visit rely heavily on Java to do their thing. At the same time I found out that iTunes also uses Java. You can guess where I’m going with this.
Ok, I’ll forgive Apple for using Java in iTunes. But webbies, especially discussion boards, use PHP. It runs server side and doesn’t fuck my machine up.
