The instant nature of the internet drives an apparent need for news to be put up as quickly as possible. Here's a minor example from my morning place. These are two Twitter entries placed right next to each other from different news services. Note the difference in the body count. I know that these types of counts are notoriously inaccurate and that a 10% difference in this case doesn't really detract from the main story. But it is illustrative of larger gaffs in news coverage which can result from this rush to be the first on the net with the story. If your report is more than 17 seconds ago, it's old news.
