At Facebook we love tools that allow you to see what people around the globe are searching for or discussing on blogs, such as Google Trends or Technorati. We thought it would be cool to show trends on the public and semi-public forums across Facebook (also known as Walls). Today we’re announcing the launch of Facebook Lexicon, a tool where you can see the buzz surrounding different words and phrases on Facebook Walls. Lexicon pulls from the wealth of data on Facebook without collecting any personal information in order to respect everyone’s privacy.
Smart move, not unlike the PR value gained by Zeitgeist (hell, that one launched me on the book, after all!).
