The vast vast vast majority of snaps are not nudes or drunken debauchery. Most of them are just mundane moments of life: I saw a building while walking down the street, or, here's my lunch.
Snapchat is useful and popular because it is a way for people to say hi to their friends without having anything to say. You just take a selfie with a filter, make a face, and you're done. This lets you feel close to your friends without having the pressure of actually having a conversation topic.
The genius of Snapchat is that because photos are ephemeral, the bar to create content is as low as it gets, which results in orders of magnitudes of more content creation and sharing compared to platforms like Instagram. On Instagram, you spend all of your time obsessing over the perfectly angled and filtered photo, hoping to get as many likes as possible. As a result, you'll post on Instagram once a week, but you'll post 5 times a day to snapchat. That's a two-orders magnitude of difference in usage, which is why Snapchat is so successful.
