Facebook Makes Up 52% of Sharing on the Web | Commentary and analysis from Simon Dumenco – Advertising Age http://adage.com/article/the-media-guy/facebook-makes-52-sharing-web/231528/#.TufxpCbab5c.pingfm
■According to AddThis data, Facebook accounts for 52.1% of sharing. Given the size of AddThis’ data set, that number’s probably a solid proxy for sharing across the entire web.
■Twitter was up 577% this year and accounts for 13.5% of sharing, per AddThis Analytics.
■Usage of Google’s +1 button grew in 2011 but has plateaued, according to AddThis. And if you want to feel bad for Digg and MySpace, just take a look at their depressing shrinkage numbers.
■AddThis tracks what browsers its users prefer. Great news for Google’s Chrome: It’s been on a hot streak and actually overtook Firefox last month.
■An astonishing 28% of all AddThis shares on May 1 and 2 were about Osama bin Laden’s death. (The news broke in the U.S. on the evening of Sunday, May 1, but he was technically killed on May 2, Pakistan time.) Other news and events that were widely shared on AddThis were the earthquake on the U.S. East Coast, the Japanese tsunami and earthquake, the death of Steve Jobs, the launch of Occupy Wall Street, the British royal wedding, the resignation of Hosni Mubarak, Hurricane Irene, the final Space Shuttle mission and the Super Bowl. Also, somebody named Kardashian got divorced or something? Ring a bell?
