Here at Hive Development, I'm currently working on the GWT based UI for a new website/RIA monitoring service called SiteAlright. I recommend you head over and check it out. As you might expect we try to follow best practises when developing our apps and there's been quite a lot of talk recently on GWT Google Groups regarding the use of elements from the recent talk by Ray Ryan at Google I/O 2009.

The HelloWorld is very long : you should use all these best practices only if you build a large application.
