I just wanted to say that I have been using GWT since 2009 and I never thought about sharing how much fun GWT has brought to my developer life. So I am doing it now :-)
To be honest, there are some libraries/toolkits out there that rise above the others. They have this intrinsic quality, they are open instead of restrictive on your coding style and when you need to take the extra mile in your dev work, the framework goes along, providing what you need. GWT is definitely among these.
GWT is the reason that I started browser UI development as a Java backend profile.
I am so happy GWT is still among us and I will be continuing to use this framework for many years to come.
Thanks for this great framework!
