Because you'd get overwhelmed if you saved every little moment of your day?

Sometimes those moments are worth sharing with people because it brings you closer or continues a conversation. However, like with a conversation you don't need to remember the exact words sometime later for that conversation to have been worthwhile.

Because it's not about creating anything, it's just like conversation. You don't remember 99% of the conversations you've had in life either, and you're content not recording them.

That's the part I don't like about it. The president's car passes at a rally, do I take phone video or snapchat it or just enjoy the moment?

A lot of people i know default, including me, to using snapchat as their main camera in most situations. You can download whatever you take a picture of through the app and choose not to post it at all. It has all the features i need from the camera plus some basic photo editing. Also the reverse isn't true: I cant take a picture through the normal camera then choose to post it to snapchat. this both locks you into using the Snapchat camera and ensures that most pics you see on snapchat are taken in the moment, which is very important to the app. btw I'm 23
