What does this mean?

When a News Agency uses Twitter to release breaking news.

And they are following some 1500 people.

What does this mean about gathering the news?

Have we once again collapsed the time of when an event is happening and when news break?

I keep thinking about how I could have used Twitter when we had an attack on our compound in Saudi.

The AP and BBC called some people on the compound 3 hours after the event. Would Twitter have changed that?

What implications if any does this have on society?

(Just thinking out loud)
