Australians will have to wait for the newly-hatched Twitter Local Trends feature - which went live overnight - to come down under.
The feature is designed to keep Twitter users up to date with the hottest topics being Twittered in a specific geographic location. The company has not disclosed when Australia will be added to the feature, saying only "we're working on it".
Twitter's Jenna Dawn said on the company's blog site the feature will allow users to learn "about the nuances in our world" and discover relevant topics.
"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 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 Sao Paulo, Brazil?"
The feature includes 13 cities and six countries.
RJMetrics yesterday released a study showing that the number of Twitter users has climbed to a lofty 75 million, but that the growth rate of new users is slowing. The study also found that a lot of current Twitterers are inactive.
According to the findings, only 17 percent of all Twitter accounts Twittered last month. That's down from more than 70% in early 2007 when Twitter was a fledgling company with far, far fewer users.
The report said that Twitter has between 10 million and 15 million active tweeters.
