The Google Web Toolkit (GWT) is now open source under the Apache 2.0 license. This means that I might be starting to use GWT when I find it appropriate.

I personally hate using JavaScript because of the difficulty of debugging it (and making sure that it works for everyone) and because of not wanting to force people to run JavaScript in their browsers (I myself run NoScript). With GWT I can get around the first problem by writing in Java and hence use JavaScript when there’s no feasible alternative.
