It's a story I've been morbidly keeping an eye on because I used to know someone at NotW who I suspect might get caught up in it.
As usual Twitter is the index to any new stories/angles but I've been surprised that the 'conversation' isn't gathering in it's usual co-ordinated way around a hashtag or two. I've been monitoring the most obvious keyword phrase: 'News of the World', and there's plenty of tweet activity...but despite my asking aloud if anyone had seen a hashtag yet, it is now lunchtime and there has been no sign of one.
I think originators - in this case, newspapers - are missing a trick here.
If you are going to break an exclusive story (for other kinds of originators it could be a scientific paper, or a product launch, or a survey, etc) you should always give it a hashtag. Like the grit in an oyster or a hailstone, twitterers need a hashtag to build the conversation around.
Why didn't the Guardian simply print #NotWphonehack at the bottom of their article. Then the online community would know where to gather to discuss it.
As @Aleksandr_Orlov says: "Simples!"
Afterthought: Actually #NotWtelhack would be shorter :)
