Orionblastar, thanks for your thoughtful advice. Yes, we've debated using background checks, but I worry they provide a false sense of security. Truth is, it's not very hard for a bad guy to fake his way through a background check. Instead, we're experimenting with what we call "Mommy Dating." A mom (our users are all moms so far, except for me) can browse selfie videos of other moms in her neighborhood. We believe that "a video is worth ten-thousand words." If she sees a mom with whom she feels chemistry, she can set up a coffee date at a public place, then perhaps a playdate, before deciding whether to share childcare. I have great faith in a parent's intuition about other parents, and I see our primary job as making the introductions and letting parents create their own village as they see fit. Hope this clarifies, David
