Publish a directory of the Twilio apps

It'll be great if Twilio maintains a directory/showcast of the applications built using Twilio. The contest winning applications are encouraging, but they are limited! Unfortunately, there aren't many ways to advertise a phone service, and Twilio hosting a directory will bring more publicity to the apps and to Twilio service as well.

Needless to say, it should be an opt-in program.
