The challenge for them (which Ben has addressed on Exponent previously) is that their promise to their users historically has been anonymity. That directly goes against what brand advertisers need to succeed. At least DR players can see performance metrics even if they can't easily identify audiences. But for brands, they need audience data. So Snapchat has an interesting challenge on their hands...how to get more info from their users and convince them not to leave in droves when that promise of anonymity is taken away they make it available to advertisers. And I'm not talking about advertisers getting direct access to uniquely identifiable users. I'm talking about Snapchat collecting and storing that data. Their recent ToS changes make it seem like they are moving in that direction.
