>Snap's data has real value
My only disagreement is that its all fake usernames. The friend graph is not as accurate as its like Kik, Myspace, Instagram and twitter in that people will add random people from all different sources, and make connections as there are no real threats to "real life" and "online life". with facebook you at least have a more signals into a "real life" graph and with twitter you have an interest graph. With Snap I don't think either of their signals (stories, friends) are as good.
