"One of the many undying questions from web publishers, marketers, and regular web users is "what makes something go viral?" which, coincidentally, is also something Microsoft is working on.
Today the company revealed a new research project called ViralSearch that uses a search engine to identify the most popular content on Twitter.
ViralSearch scans billions of pieces of information, including news, photos, and video, and assigns a virality rating to the most popular topics based on how the content was shared via Twitter".
