gone.cx
most of the internet keeps everything by default. gone.cx doesn't.
the internet refuses to let things die. the default architecture of the web is endless accumulation — storage is basically free, so most systems just append forever. deleting something takes deliberate effort, and most of the time nobody bothers.
gone.cx exists in the opposite direction.
some of what's there disappears while you're still looking at it. what's true today isn't a promise about tomorrow.
if you want to leave something there, go ahead. if not, that's fine too. it's not going to remember you either way.
