Have you never made a joke before that some random person might not like and get offended by it and try and attack you for it? Have you never said something that you have looked back upon and regretted saying it (whether you were just young and immature or just not thinking clearly)?

Do you also not do those things over common communication channels outside of talking face to face?

I'm genuinely curious because I literally don't know anyone under 30 that has never done anything that they did not want recorded in history forever.

It's not that I have posted anything on facebook/instagram/snapchat... that is really that bad/embarrassing. If it were all posted on the front page of the NYT I would probably go through life just as normally (albeit, quite a bit embarrassed by it). I would just prefer to minimize that risk.

That's where snapchat fills the niche. It allows me to speak more freely with others with less fear that everything I say and do will be pulled up years later completely out of context.
