Social media monitoring company Brandwatch have created a cool data visualization Web tool, which reveals what twitter user sentiment on the England and Germany squads. The chatter is updated in real-time as people tweet about different players.
Unfortunately (or fortunately), there is no such visualization available for the Ireland squad.
As TheNextWeb says:
If nothing else, this is a good example of how, with the right presentation, social data can be aggregated and used to give a good overview of national sentiment around an event.
