Google Now automatically caters results to your prior searches, but manual customization of what it serves up is a little clunky. You can either toggle fields of interest on and off in the service's settings or click a box on cards or news sources to indicate your future disinterest. But now the tech titan is testing out a more active method to tell the predictive service what you'd like to see with "Explore Interests." Just don't expect it to come out any time soon, as Google has "nothing to announce" at this time, a spokesperson told TechCrunch.
