I did't delete all my accounts because I've said something wrong. For the same reason people don't spring clean their home because they're getting rid of murder evidence. It's all about getting rid of the feeling that you and your thoughts from 20 years ago are all over the place. Little pieces of you are everywhere all over the internet.

There's a dread that a user feels when they realize they don't remember what they said or who they were 10 years ago, but the whole internet does.
