SalahEldeen and Nelson looked for tweets on six culturally significant events that occurred between June 2009 and March 2012. They then filtered the URLs these tweets pointed to and checked to see whether the content was still available on the web, either in its original form or in an archived form.
They found that the older the social media, the more likely its content was to be missing. In fact, they found an almost linear relationship between time and the percentage lost.
A few weeks back bitly posted some interesting data that hints when people use different social networks. Today’s stupid idea for not playing Minecraft all day involved creating a CSS3 time display webpage that overlays current time over the graphs published by bitly.
Tumblr is apparently the party network for evenings and weekends so cheers to you guys!
