We launched our application directory to a share of users March 31, and finished rollout to 100% of our users April 4. We currently have 229 applications in our public directory.
The gallery is actually live as well as the viral channels. The reason we sent you a screenshot for the gallery is that we are ramping up the platform release to users over the course of this week, so not every user will see the platform yet when they log in. We are already getting ready to release to 50% of our userbase today and are optimistic we'll be fully live soon. We'll post to our developer blog when that happens.
