The decaying web and our disappearing history

Posted by in categories: information science, media & arts, philosophy

On January 28 2011, three days into the fierce protests that would eventually oust the Egyptian president Hosni Mubarak, a Twitter user called Farrah posted a link to a picture that supposedly showed an armed man as he ran on a “rooftop during clashes between police and protesters in Suez”. I say supposedly, because both the tweet and the picture it linked to no longer exist. Instead they have been replaced with error messages that claim the message – and its contents – “doesn’t exist”.

Few things are more explicitly ephemeral than a Tweet. Yet it’s precisely this kind of ephemeral communication – a comment, a status update, sharing or disseminating a piece of media – that lies at the heart of much of modern history as it unfolds. It’s also a vital contemporary historical record that, unless we’re careful, we risk losing almost before we’ve been able to gauge its importance.

Consider a study published this September by Hany SalahEldeen and Michael L Nelson, two computer scientists at Old Dominion University. Snappily titled “Losing My Revolution: How Many Resources Shared on Social Media Have Been Lost?”, the paper took six seminal news events from the last few years – the H1N1 virus outbreak, Michael Jackson’s death, the Iranian elections and protests, Barack Obama’s Nobel Peace Prize, the Egyptian revolution, and the Syrian uprising – and established a representative sample of tweets from Twitter’s entire corpus discussing each event specifically.

It then analysed the resources being linked to by these tweets, and whether these resources were still accessible, had been preserved in a digital archive, or had ceased to exist. The findings were striking: one year after an event, on average, about 11% of the online content referenced by social media had been lost and just 20% archived. What’s equally striking, moreover, is the steady continuation of this trend over time. After two and a half years, 27% had been lost and 41% archived.

    A very important piece of early Internet history was lost in 2009 when Yahoo intentionally deleted 38 million personal websites (GeoCities). These were personal websites started in 1994 which incuded family histories, journals, poetry, etc., which many people permanently lost. To me this was the modern equivalent of the burning of the Alexandria Library. See: http://en.wikipedia.org/wiki/GeoCities

    What does this have to do with safeguarding Earth? I think you are on the wrong blog.
