I read this Dan Moore blog entry a couple of weeks ago where he asked this same question and it seems to come up quite often on the GWT developer forum as well. It is an important question to answer because it is one of the first things people ask when evaluating whether or not to adopt a specific technology. The Google Web Toolkit has now been out for more than 1.5 years, so what have people done with it in that time? I took a look at this older list by Mark Volkmann and a couple on the developer forum and came up with my own set of GWT applications I would use, if I was showing off GWT to someone else. Here they are (in no particular order):

Pibb
JanRain

Pibb is a GWT based web application that combines the best features of instant messenger, email, chat and message boards. It supports OpenID, a lightweight protocol, for single sign-on and portable identity.

Ryan Dewsbury

KDice is another free, multi-player strategy game by Ryan Dewsbury. It is based on Taro Ito’s Dice Wars. Gameplay in KDice is a simplified version of Risk with the primary goal being to defeat your opponents by conquering the entire map.
