Will Social Networks lead to a Community Cloud? On Thursday 25th March 2010, people from an estimated 200 cities across the globe will come together to celebrate and support the second Global Twestival. Defined by Twitter as a way to take part in a global event that transforms lives, Twestival was created last year by London based Amanda Rose, an events-minded entrepreneur, who believed that Twitter’s users could be brought together for the common good. Ms Rose’s creation resulted in a series of worldwide off line events – from concerts to knitting groups – that raised over $250,000 for the chosen beneficiary – Charity:Water -  and brought worldwide public awareness to the global water crisis and the devastating fact that over 1 billion people lack access to clean water.
