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 apps such as Birdfeed, Seesmic Web, Foursquare among others and those apps implemented Twitter’s GeoLocation API all your tweets will then be tagged with your current location. Seeismic has implemented geotagging features already. So if your using it as a desktop client for Twitter, you might want to check out how this geatagging feature goes.
So, 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. ReadWriteWeb has several suggestions and creative ideas, you might want to check them out.
You can enable geotagging on your Twitter account by going to the Settings, and selecting the enable geotagging option.
