The new home page of  Twitter say it all. Real-time search is coming and  permits to “share and discover what’s happening right now, anywhere in the world”. Twitter has defined itself the Pulse of the world and has ambitious targets, 1 Billion users by 2013 with a user being defined as a “unique individual having a conscious twitter experience in a given week.”  The leaked Twitter documents published partly on TechCrunch gives a nice overview on the strategy and plans for Twitter. Many people said there was no business and no business model, well it is coming and it seems a very strong value proposition.
