Washington: Facebook users in the US can let the world know they voted in the US presidential election Tuesday, with results displaying on a real-time map on the popular social networking site.
"This map is a representation of people on Facebook who clicked an Election Day prompt to share with their friends that they`re voting in the 2012 US election," said the Facebook team in a post on the website.
While Facebook masks the identity of which users voted, other information on those who self-reported their trip to the polls is available, such as their age, gender, and geographic location.
Facebook`s team will also use its so-called "Talk Meter" to monitor and measure overall chatter and the most used terms and phrases on the site during Election Day.
Facebook ranks topics on a scale of 1-to-10 and posts results on its US Politics on Facebook page.
