Some other interesting things that I noticed was that people were making jokes about Foursquare leading to the finding of Bin Laden. As time went on, people started started using Foursquare to check into places associated with the death of Bin Laden. Some people were checking in to the location where Bin Laden was found, while others were checking in to a “Post Osama Bin Laden World”.
By 10am(EST) this morning I was able to find 11,570 tweets that made reference to Foursquare and Bin Laden or were check-in’s tweeted out that were related to Bin Laden."
