Google have added a Buzz layer to Google Maps. If you select 'Buzz' from the 'More' drop down menu in Google Maps you can now view the latest real time updates posted to Google's microblogging service.
The new layer lets you view the latest geo-tagged comments made to Buzz. The benefits of viewing near real-time comments on Google Maps may not always be apparent but the new layer should prove really interesting when locations are in the news.
For example, if you zoom into the Eyjafjallajokull Volcano in Iceland at the moment you should be able to pick up a few recent photographs of the volcanic eruption posted by users to Buzz.
