Tweeting Carnival to keep you safe
Europe's biggest street party is a litmus test for the Met.
With the Olympics just two years away, it shows the world how British police handle large-scale events.
Carnival 2010 is expecting more than a million revellers over this August bank holiday weekend.
It's tiny compared with the number of visitors predicted for London 2012.
Yet this year for the first time, Scotland Yard will be using a Twitter account to communicate with the crowds.
So yes, even the Met is embracing the social media revolution.
It's something the capital's police service apparently tried out during the Climate Camp demonstrations last August and again they think it'll be a good idea to connect with the masses.
Well, at least for those who have succumbed to tweeting. It's currently all the rage in BBC London's office in Broadcasting House . I hear nothing else now but: "Have you tweeted today?" Help!
Anyway, I've just been reading the Met's foray into the digital world (https://twitter.com/CO11MetPolice) and it's a mix of warnings/advice and on how to stay safe.
Will it work? Are you hooked on Twitter? Is it taking over your life?
