It seems to me that people building LAMP, Ruby, django, or other applications think of themselves more as building web applications with whatever technology tools they need to use: web services,
cronjobs, MySQL, ruby, PHP, python, maybe some Java: whatever. What matters is getting the web application working.
People who using Java see themselves primarily as building Java applications that happen to have a “view” (as we OO head-jobs would call it) that’s the web.
I can't really quote just a part of the article and do it any justice; read the whole thing. Anyway, this is one aspect of what I refer to as The Java Bubble.
