Interesting that others (eg Paul M Duvall in his dzone refzcard) refers to dark launching as:

You are right, there is nothing like production unless someone has gone through the pains of replicating an entire production environment (which you may not see in the case of massive deployments). Dark launching is adding another step in the deployment process. It is done before the new feature is made available to a group of users. You can gradually increase the number of users in the group.

Since the feature is not visible to the users in the case of a dark launch, you will not see any complaints logged by users. The onus is on the production support team to monitor the system and review the logs on an ongoing basis to discover any problems that their infrastructure is facing.
