I believe FB messenger now has secret/disappearing messages as a response to snapchat, but before that it was a pretty clear distinction: if I send you a goofy selfie on snapchat it's gone in 10 seconds. If I send you a goofy selfie on messenger, you could always scroll up to see it again. And share it with others if you so choose.

I guess the part I'm missing is why you care whether the goofy selfie disappears.

It's psychological. As soon as you put something on FB, Twitter, etc. it's no longer "yours". Snapchat makes conversations and pictures disposable. It's just fast and ugly. And it powers the app by nudging by users into creating content to send to a friend without having to worry about rehearsing for the perfect picture/tweet/etc.

Also it's private. Facebook is mainly used by people with friends and family. Celebrities/notable figures rarely interact with others outside of Twitter. But even with Twitter, the interactions are permanent -- even when tweets are deleted.

On and it's great for sexting, which let's not kid ourselves, was the original appeal and still is for a lot of people in their target demographic.
