Editor's Notes
- #2: In the crowded world of web technologies is often hard to decide which one suits better our needs. We think we have found a very good solution to do cool web sites with complex logic that requires javascript. Gwt is a very good product, but till recently it was a problem to use it on clean web2.0-like sites. We think that it's possible to do it in a simple way but it's still not widely know. Using with UiBindings and TDD. We did 2 applications: a CMS and a Google Appengine one. I'll talk about our experience, what we learned, and we'll share the complete code for an example application.
- #3: Blueprint experience Some raw data:

- #10: Gwt + easier to debug no new language to learn easy to unit test client logic Gwt - steeper learning curve basic gwt is "ugly" big js app to download (once)
