Clever designers understand that Snapchat’s “shitty user experience” is an asset to its devoted teenage fanbase. By being unintuitive, the app filters out any users who don’t have the time and motivation to untangle its quirks. Namely, parents, teachers, and anyone uncool enough to ask how to use it.
Teenagers are wonderfully, cruelly honest about their use of slang to exclude non-teenagers.
Academics and experts, less so.
