Events like the earthquake in china or the Hudson river plane crash have shown that Twitter is the place-to-be for real-time information.
1. Why does Twitter enable such a fast spread of information? Has it to do something with its topology (compared to other social media) or is it only because of its short-message-style?
2. How is Twitter changing the media landscape? Are there still news reporter who do not use Twitter? Why?
...need some input. Thanks a lot!
