Leskovec picks this lucky person by compiling and analysing all your online social activity. Tweets, retweets, friends and likes, he looks at them all. With about 50% accuracy, he can predict the people who will make their way to your friends list.
50/50 odds may not sound that great, but this social research tool is still in its infancy. Give it a year and improvements could lift it to an accuracy level that’ll creep you out. [IT World]
