The disappearing web: Information decay is eating away our history
One of the characteristics of the modern media age — at least for anyone who uses the web and social media a lot — is that we are surrounded by vast clouds of rapidly changing information, whether it’s blog posts or news stories or Twitter and Facebook (s fb) updates. That’s great if you like real-time content, but there is a not-so-hidden flaw — namely, that you can’t step into the same stream twice, as Heraclitus put it. In other words, much of that information may (and probably will) disappear as new information replaces it, and small pieces of history wind up getting lost. According to a recent study, which looked at links shared through Twitter about news events like the Arab Spring revolutions in the Middle East, this could be turning into a substantial problem.
The study, which MIT’s Technology Review highlighted in a recent post by the Physics arXiv blog, was done by a pair of researchers in Virginia, Hany SalahEldeen and Michael Nelson. They took a number of recent major news events over the past three years — including the Egyptian revolution, Michael Jackson’s death, the elections and related protests in Iran and the outbreak of the H1N1 virus — and tracked the links that were shared on Twitter about each. Following the links to their ultimate source showed that an alarming number of them had simply vanished.
