When Snapchat was redesigned to place stories alongside chats, instead of alongside celebrities and content, I was happy. Happy because now all the things I go to Snapchat for are separate from the stuff I don't care about.
Apparently, I was in the minority. Younger users have been vocal in their disapproval of the change, so much so that Snapchat may be putting it back the way it was. In this case, it would be better for Snapchat to leave things alone because of a strong vision, rather than being tossed about.
Good designers show users what they want; users are often terrible at understanding or explaining what they want.
