You write: 'to run this code, you'll need to create an application.'

WHY?

What is the difference between a script and an application? And what was special about the WorldlyGreeter example that warranted an application and couldn't have been done in a script?

Cheers,
Carsten.

I think the authors wanted to introduce the application concept at this point. As the 2nd and 3rd chapters are kind of a whirlwind tour of Scala, this is not unreasonable, albeit a little contrived. So, while you're right, there is nothing that couldn't be done as a script in the application, there is also the pragmatic element of showing how to create an application for the sake of showing us an application.

I made a similar comment via the "Suggest" link on the page. It would be useful to see a list of the Errata/suggestions received so far (with any relevant feedback from authors). No need for a fancy solution like the Pragmatics have - a plain text listing updated about once a day would be enough.
