The Twitter blog has announced a new feature for the micro-blogging site, with the launch of Twitter Places. This now allows users to tag their 'tweets' with specific place locations, so that readers can see where the tweet was made.

Users can also click a Twitter Place within a tweet to see other recent tweets posted from a particular location. There is also integration with the Foursquare and Gowalla services, which are increasingly popular location-based services, plus an API to allow developers to integrate Twitter Places into their applications.
