After more than 8 years of coding in Java, I had to pick up Python (and Django) so as to start using GAE for my startup.
Now, looking at those sample code in Java (and JSP) and the related XML configurations for GAE, I don't think I want to go back to Java - unless I am paid to do so, say for services.
How do you define troll? A blanket statement labelling an entire technology with a pejorative without any justification or explanation seems fairly trollish to me.
However both of us are certainly off-topic and should be downvoted heavily :-)
