The horrendous events in Mumbai prove once again that just when you thought you'd seen the worse of terrorism, you haven't. But sitting at home on my sofa, shocked by the brutality of it all, I was sucked into the power of breaking news on Twitter. Watching tweets come in from those at the scene witnessing it, was both powerful and humbling. And a service like hashtags makes it so easy to follow the stream of a particular story. I honestly can't see how mainstream media can compete with the immediacy of this – they really need to incorporate it into their own news reporting or they'll just be left behind.
