All data leaks. This is not a property of the internet, but a property of data — just ask the Pharaohs of Egypt about their secret tombs. Data is observed (and therefore replicated), or obliterated through time. All public data has the power to replicate on its own. That may seem a strange statement, but I mean that it doesn’t have to be pushed to be preserved. It can be copied, learned by new people, archived in strange places, and ultimately passes out of control.
The hard part of professional journalism going forward is writing about what hasn’t been written about, directing attention where it hasn’t been, and saying something new.
