In a Monday announcement on its blog, the popular microblogging site Twitter said that its ‘Twitter Places’ feature, which was unveiled in April, is going ‘live’ globally. The feature will allow Twitter users to know from which specific location a post has been written.

Pegging the Twitter Places release to the World Cup, Twitter revealed that the users will be able to tag their posts with their exact location – like Alcatraz or the Columbus Circle Whole Foods – and others can search for all the posts written from a particular location.

At present, users can either go to the Twitter site or use their mobile phone app to tag their location along with their tweet – picking a current location, or else entering a new one from a list of places. As a result, anyone who reads a tweet sent from a specific location can click on that location to view other recent tweets linked to the location.

Even marketers can use location information for reaching potential shoppers who may, for example, be in a rival store or restaurant.

Noting that Twitter Places is a significant step in the endeavors of Twitter founders to develop new ways in which people can find the messages that are most relevant to them, Twitter’s co-founder and CEO Evan Williams had said at the company’s Chirp conference in April: “Where you are defines what you’re interested in.”
