Dear Google,
*I am ½ of a 2 person dev and design firm, oyoaha. We always speak in the first person singular.
I use GWT as a graphic design tool.
Deploying a product using GWT (or even prototyped something neat)
proof of concept for clients (way more interesting!)
http://jorg.oyoaha.com/
http://oyoaha.com/easydynasty/
actual deployed projects (with happy happy customers)
http://www.artorganism.org/
http://www.firstthursday.org/
Reporting and debugged some of the issues
aha! that's a trick question as GWT is perfection!
(well I did found some but made my own work around I never communicated. will try to be better next year)
Submitting a patch (to help Make GWT Better)
I did make a patch but it got fixed before I had a chance to submit it!
Participating in the discussions on the developer forum
but I am way too shy!
seriously I did talk to other people about GWT this last year. I even started a drupal module to integrate GWT with drupal http://drupal.org/project/oagwt
