As the number of your Facebook friends and Twitter followers grows, a new crop of online services can help you organize your social-networking buddies into smaller groups.
One such service, Katango, says it has figured out a way to automate the process. Katango, which has been available as a free iPhone app since July, launched a Web version Wednesday. The service sorts your Facebook friends into groups based on a formula developed by Yoav Shoham, a Stanford University computer science professor. Shoham, Katango’s chairman, said the company wants to do for your social experience online what Google’s search formula did for Web pages — organize them based on a useful algorithm. Its friend-grouping formula accounts for which of your friends are commonly tagged in the same photos, comment on one another’s posts and so on. The Associated Press
