We're using it for this site: http://www.liveleader.com/. See the live demo if you want to have a look at an app built from scratch in GWT.

To me, the single biggest advantage of GWT is that I can use Java tools for development, refactoring and debugging. As a Java developer with limited JavaScript skills, that's a very big plus. And using Java all the way means that I can share code (and pass objects) between the client and the server.

The generated JavaScript is not very search engine friendly, but GWT apps can be popped into a regular HTML page. You should probably be using GWT for app-like stuff, not things you want Google to pick up.

Submission + - Amazon offers SimpleDB - for-pay web data storage

CREATE — to make a new domain,

GET, PUT, DELETE — to manipulate your domain, and

QUERY — to find things within the domain

Data is stored in cells, that contain multiple attributes. A single attribute may contain multiple values, for example: (name, bob), (favoriteFruit, apple), (favoriteFruit, banana).

Another interesting tidbit is the cost structure — you pay for how much data you store, how much you transfer, and how much CPU the database uses while manipulating your data. While I'm not convinced it'd be practical for systems that store lots of data and manipulate it constantly, one might imagine small apps that can cache their data effectively taking advantage of the service."
