This fracturing of context is, I suspect, peculiar to these early decades of online writing. It’s possible that, in the future, webmentions and the like may heal that up to some extent. But everything from the 90s to today is going to remain mostly broken in that respect. Most of what we said and did had ephemerality long before apps started selling us ephemeral nature as a positive advertising point. Possibly no other generation threw so many words at such velocity into a deep dark well of ghosts.
