Haha- I couldn't be happier to be rid of it. I used GWT for a couple of projects. It's a good useful thing but it was like being back in the 80s (or mayber early 90s)
Google Web Toolkit was great for putting your java in your javascript. Those were the days. I didn't really know Java or JS that well but I could write stuff! We actually used it for projects at Google. Plus anything interesting in java was always not implemented in GWT.
