There's product placement. He namedrops "Treller" and "VSCO". The article isn't "How to upgrade your style", it "How to become a Snapchat user." Even his conclusion is "I'll try more", just like you tell yur teacher when you've failed and you know you'll fail again. I don't doubt the person is authentic, but I wonder how much he has worked with BuzzFeed to tune the article.
Still, 1. Snapchat's design is remarkable for its hidden features that you discover by social-networking, and 2. it's a much more interesting, funny, interactive press release presenting the features of a product than any other start-up I've seen. Next product video I make, I'll make it this way.
