I understand all that, but I can almost positively assure you that my shitposting isn't super important to have saved, other than for personal reasons. I have a backup of my site from the time, I've held onto it, for sure. But after I die, I'd really rather it stop existing, just like I do.
And we really don't need to remember every business that started and failed within two years. I certainly don't see a great reason to document my dad's shitty used car salesman antics of my youth with his own business. It's honestly also best forgotten by time. There's more worthwhile and prolific con-men to write about and keep documentation thereof.
And frankly, if I don't want my past to be on the internet forever, that should be my choice. Just like in the past, pre-internet-and-computers, if I didn't want to share my writings with anyone before I died, I could burn them properly to make sure they were lost to time.
My original intent was literally meant as a Devil's Advocate counter-point to the point of the article. Sure, we can't tell from where we sit what's important to the future... so maybe trying to save everything is a fools errand to begin with, since we don't know what's worthwhile to save? Saving literally everything for the sake of the future seems ill-considered. Once again, I assure you my shitposting with my friends really isn't all that important culturally or socially.
EDIT: Also this is a cute philosophical 180 degree turn from 14 years ago when numerous scientists, philosophers, and organizations were positively up-in-arms and scared about the prospect of the internet meaning "the end of forgetting" and not being able to move on from your past and grow as a person because your past life on the internet would always come back to haunt you.
