Ever wonder what your neighbors are tweeting about? A new feature that Twitter is testing with some iPhone users may help answer that question. If you let Twitter see and use your location, you may have access to a new timeline called ‘Nearby,’ which shows recent nearby tweets, whether you follow the tweeter or not. ‘Nearby’ shows a map with a blue dot marking your location, along with a timeline of recent nearby tweets that pair with icons on the map noting their locations. Tapping an icon pulls that tweet to the front of the screen. Twitter is always looking for new ways to improve discovery, and ‘Nearby’ looks like a new way to do so – while also keeping tabs on where you are. Twitter began letting you add your location to your tweets in 2010, but the feature disabled by default and must be manually turned on. If you want no part of this, disable location sharing in the “Location Services” tab under the “Privacy” section of the phone’s Settings.
