> If no one can read an a book what good is it?
Plenty of good. As a writer myself, sometimes just having these thoughts put out into form is a very gratifying process. When the inspiration hits you, nothing feels worse than not being able to express these thoughts and feelings in a way that feels appropriate.
Likewise, sometimes people write dumb things in a fit of passion. They write something that is a blemish on their otherwise fine history or that no longer reflects what they believe anymore.
While I'm on the side of the Internet Archive here, I can definitely appreciate that it's not an open and shut case. Sometimes the yearning for information to be free is at odds with our want for privacy. Tools like Medium, Twitter, Facebook, and other social media are like the gun in the house to someone suicidal (to use a very bad analogy) - an easy and convenient tool that allows for a very bad spur of the moment decision to be made.
I know I've done stupid things on games and on message boards in the past, and I'm only so lucky that this data likely isn't available anymore. Some of it was me being a dumb kid. Some of it was me just being an angry kid, but I am 100% grateful that this information is only remember by myself and a handful of others. A very different past me had a very stringent set of beliefs which I now have come to accept were very bad beliefs, and I did bad things in general as a result of them.
Is it really fair that I have the benefit that time forgot all these dumb things I've done simply because I was born before a time when Twitter/Facebook were common place? Before data permanence was really possible on a global scale? I'm open to the idea of some review on archiving data like this; I want the Internet Archive to be able to archive this stuff, but it would be really nice if there was a way to vault it for a reasonable period of time as well by request. Otherwise, you end up in a position where no one wants to write or produce or do anything in a fit of passion as a result of knowing that everything is permanently preserved.
I don't have an answer aside from "vaulting" the data, and I don't think that's a good answer. But I also don't think it's black and white like you're trying to make it.
