Thanks for taking the time to read our application and comment! We totally agree that finding new and deeper ways to engage parents will be a critical component of making the program more adaptive over time. Gamification is something that we think about quite deeply -- if you receive our texts, you'll notice that many of the activities we recommend center around parent/child play. Moving forward, I think that our efforts to promote deeper engagement and interactivity will center around making the in-text experience richer overall. As you noted, text messaging is a very practical channel for reaching parents where they are at, regardless of their income, and equal access is core to our social mission.
