Maybe that the app is garbage. I agree that it's garbage yet also somehow delight in the fact that it proves app purists (use Apple UI guidelines, slickness is paramount to user experience) utterly wrong about the criteria for a successful app.
No one cares how well the Skinner box is written, just as long as the right levers can be pulled and buttons pressed.
I have no problem with snapchat per se, one of the most brilliant things about it is that it recreates the ephemerality the world has always known, which for some reason the internet pioneers got in their brain needed to be replaced by archivalism that defined the first 30 years of the public internet. It's actually quite brilliant to bring this sort of casual conversation to a social network, and it's obvious why it resonates with teenagers as it reflects the social nature that teenagers' lives have always had.
My problem is just with the addictive nature of apps in general. Facebook is probably a worse violator than Snapchat, but in the end all popular apps by definition sort of have to do this. Call me a hypocrite since I've been obsessed with computers and tech my whole life, but something about this makes me so sad. I hope we can live in a future where we are not all glued to our phones all the time.
