It also announced a lot of new features that will make it more useful — geo-locational services, a database of places and adding metadata to posts.
One is called points of interest. People on Twitter have been able to include their general location for a while. But now they will be able to reveal exactly where they are – like at the Palace of Fine Arts in San Francisco, where the conference is taking place.
People could search for a certain location, the conference hall or a hotel where there is a fire, for instance, and see all the posts written from that spot.
This sounds a lot like the check-ins on Foursquare and Gowalla that people use to share their location.
“We’re not looking to duplicate the functionality of Foursquare and Gowalla,” said Evan Williams, Twitter’s chief executive. “We really care about content.”
