Twitter Local Trends, which the microblogging service began rolling out late last week, are now live throughout the Twitterverse, giving users the option to leave Trends at the default Worldwide setting or to choose from countries Brazil, Canada, Ireland, Mexico, the United Kingdom and the United States and cities Atlanta, Baltimore, Boston, Chicago, Dallas-Fort Worth, Houston, London, Los Angeles, New York, Philadelphia, San Antonio, San Francisco, Seattle, São Paulo and Washington, D.C.
The rollout is the latest example of Twitter using its geolocation technology, although the settings can also be changed manually via Twitter.com.

The big events that come up around the world will always become a global conversation, but what about the big events that only happen in your world or that only matter to those around you? Or the slight differences in the way Californians perceive an event, like Obama’s election victory, versus those in São Paulo, Brazil?
Local Trends will allow you to learn more about the nuances in our world and discover even more relevant topics that might matter to you. We’ll be improving this feature over time to provide more locations, languages and data through our API.
