title: To use or not to use Scala for new Java projects?
body: <p>I'm impressed with Twitter and investigating to use Scala for a new large scale web project with Hibernate and Wicket. What do you think about Scala, and should I use it instead of Java?</p>
  
  <p><strong>EDIT:</strong> And, do you think Google's Noop, Fan or Scala can take the leadership from Java in the near future, which one have chance in your opinion? </p>
