Twitter has just activated its GeoLocation feature which will let you opt-in whether you want your tweets to be tagged with your current location. The feature is carried not on your Twitter.com account but on third-party Twitter apps which will use the Geolocation API released by Twitter.

If you’re using Twitter applications such as Seesmic Web, Seesmic Desktop or Foursquare all your tweets will be tagged with your current location.

What’s good about this feature? There’s plenty actually. For one, it could spark up more local conversations between you and your Twitter followers as well as the people you follow on Twitter. You can easily find out events that are happening in a nearby locality just by checking out your Twitter timeline.

You can enable geotagging on your Twitter account by going to the Settings, and selecting the enable geotagging option.
