SitePoint is popularly-known as one of THE places for PHP articles (its PHP forum is also one of the busiest) - this shift in focus to enterprise technologies is encouraging, since I've always thought newer web developers tend to view PHP as the end all and be all to getting a serious job in web development. This is my opinion of course, and in no way should this be construed as trolling! :-)
Are you a Java developer? Come help make the Java forum (it's currently called the "Java, ColdFusion and Other Languages" forum, but that will soon change in our proposed forum structure changes) more lively. We need more members to help grow the Java forum, be they leaders in discussions or fledging newbies.
