New feature called ‘Local Trends‘ that allows users to see location-based trending topics has begun rolling by Twitter. It allows you to set a specific location, so that you can see the trends around you. Most of the time, this would be your home. However, it looks like you can change it on-the-fly if you’re traveling, for example. Moreover, ‘Local Trends‘ gives you a list of different cities and countries in which you can view trends. It’s a limited list so far — only 15 U.S. cities are supported so far. You can access these trending topics from Twitter.com, on the right hand column.
