Too much of sexual health and education is left to out-dated material, strange social interactions between terrible actors and awkward group conversations that teach consequences rather than options.
I believe an idea like this one would allow for youth to take in information from what they view as a 'trusted' source (we trust celebrities now more than ever with a new level of intimacy through social media) in the private, ephemeral manner that SnapChat provides.
I believe creating an easily accessible medium like this one would go a long way in ridding the public of the stigma that comes with these conversations. While I believe that the celebrity route is the most powerful, I wouldn't discount the power of the 'everyday' person either.
Overall, though, this is one of the most powerful examples I have been privy to.
