The Revolution Will Not Be Archived 11% of the Social Media About the Egyptian Revolution Has Been Lost In One Year. Hany M. SalahEldeen and Michael L. Nelson [email protected], [email protected] How Long Do the Links We Share Last? If twitter is the ”first draft of history”, then we should be doing a better job of preserving it. For the one year anniversary of the Egyptian revolution (2012) we revisited a sample of the shared social media content and found nearly 11% missing from the current web, and only 20% available in public web archives. Spurred by this, we sampled tweets for five other culturally imporant events from 2009–2012 and found similar rates for archiving and loss.
