Facebook Patents News Feed

Facebook has always made it clear that it does not like imitators. And now it will be able to do something about them. The social-networking Web site may be able to sue others that violate the patent it was just granted for streaming “feed” technology. The news feed, lambasted when Facebook first rolled it out in late 2006, is now a model that has spread to social-networking sites all over the Web and, for instance, is at the very essence of sites such Twitter.
