Google’s success stems from the fact that it’s so useful that you can’t live without it and so unobtrusive that you tend to forget it’s even there. In none of it’s services is this more evident than Google Now, which can make your life so much easier that it’s actually kind of unsettling. As the wannabe-Google, it’s only natural that Yahoo tries to replicate this success, which is the company is working on a new app called Index. Not much is known about the new app aside from the fact that it’ll be in the same vein as Google Now and Siri.
