We just surpassed quite a milestone today - Vaadin forum is now more active than
GWT
(when measured on 90 days sliding window). Actually we are more active than SmartGWT, Wicket, Dojo, JavaFX and ExtGWT forums for that matter - all of these with a much larger margin than GWT. Couple of “competing” framework forums are still more active, namely jQuery, ExtJS, Oracle ADF and PrimeFaces, but with the current speed - they might not be for long 
Thank You for keeping up amazing, friendly conversation and helping each other - it is what really matters!
