Twitter is bringing easy geo-tagging to its popular micro-blogging service which might give possible ways for them to make money.

Twitter Co-founder Biz Stone wrote on their blog:

We’re gearing up to launch a new feature which makes Twitter truly location-aware. A new API will allow developers to add latitude and longitude to any tweet. Folks will need to activate this new feature by choice because it will be off by default and the exact location data won’t be stored for an extended period of time. However, if people do opt-in to sharing location on a tweet-by-tweet basis, compelling context will be added to each burst of information.

Third party developers like Germany’s Twibble have already produced geo-location services for Twitter relying on user details in their profiles. Let’s see what Twitter will have to offer on their own.
