people working on appengine really want java? Isn't write webapps in java unproductive? I would figure developers would rather have ruby,php instead.
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.
The parent post is neither a troll, spam, or off-topic, and thus should not be downvoted.
A simple "no upvote" would suffice. If you disagree add a substantive rebuttal to your "no upvote".
However both of us are certainly off-topic and should be downvoted heavily :-)
Java is orders of magnitude easier to scale.
And besides, there are many people with investments in Java already. I think this is a pretty good choice.
Now, if they also added Mono (.NET) that would be great.
