One thing I noticed in following the war in Syria is how much Twitter is part of the community surrounding the war. Updates from the frontlines from journalists and local fighters, mapmakers, analysts andarmchair generals following the war from all over the world. In addition it works well together with other media such Youtube and reddit, for example.
I feel this is way the medium is much more useful for us than the free-for-all followfest many people use it as. It really took war coverage to the next (perhaps somewhat disturbing) level after what they called the ‘CNN war’ of the 1990s and put more control of the content in control of amateur communities over the traditional media.
