Twitter adding Geolocation to API

In the near future the Twitter API will be extended with the ability to geotag the tweet. The user will have to enable adding geo information to the tweet (for privacy reasons) but this will be a genuinely useful addition to the service. It will also allow a whole new slew of geo enabled applications that can get very interesting information from gthe Twitter stream.

Initially the new API will be released to a limited number of platform developers (who are generally the people writing Twitter clients) before opening it to the general public.

Twitter are also developing further additions which will enable commercial users of Twitter to gain increased functionality from the service, though @ev (Evan Williams) has said the service will always be free for ordinary users.
