This one just sent to me by a very excited Ali Daniali. Registration is now open for Google I/O 2010, and the registration site is powered by ColdFusion and Fusebox. Google, we're glad you've discovered online productivity! ;-)
It's nice to have FACEBOOK and CFM in the same URL as well! :D
Unfortunately (and embarrassingly) for Google the same ColdFusion based registration site totally failed under load for the 2011 Registration that sold out within an hour. Those of us that deal with ColdFusion know that it can scale to handle load peaks like this but I worry that next year we will see a different solution - probably running on Google App Engine - taking registrations.
