This page is one of the most controversial aspects of the newest Snapchat update.
Before the update, stories and private messages were located on opposite ends of the app. Friends' stories were listed among and next to celebrity and marketing content, on the "Discover" side. This gave users the feeling that they were friends with and had an inside connection with their idols and the brands that they admire, and was very unique to Snapchat.
Now, celebrity and ad content is grouped with news and editorial, and your friends' stories are embedded within your personal inbox.
Snap says this new layout, while perhaps confusing for users who have grown accustomed to the old version, is the easiest way to serve users all of the content that they "care about the most." The notion is logical, but many users argue it assumes a little bit too much about individual users' motivations, and removes that sense of connection with the artists, musicians, politicians, or other celebrities that they've chosen to follow.
