Write something, hit publish, and it's live.
There's no tracking, ad-tech, webfonts, analytics, javascript, cookies, databases, user accounts, comments, friending, likes, follower counts or other quantifiers of social capital. The only practical way for anyone to find out about a posting is if the author links to it elsewhere.
Allen Jacobs notes in his newsletter that it appears you can’t edit what you’ve posted or take it down.
What you publish is also not scraped by the search engines. So, as the site says, “you can scream into the void and know the form of your voice is out there forever.“
