DWR has just had cool contribution from InfoQ. As part of the development of InfoQ Alexandru created a neat tie-in for WebWork that allows you to execute part of a WebWork action using DWR. The integration was fairly easy before, but it is even easier now.
InfoQ have used DWR for part of their user interface which is neat. I've got lots of examples of DWR being used in large internal projects - it's nice to see it being used in more large public projects too.
I've also noticed that dzone - the new site from JavaLobby is also using DWR for their Digg like voting system.
