Millions of people are talking all day, every day on twitter. But what if all those people came together and actually did something? Enter Twestival, a global event organized through twitter taking place on February 12th. Over 100 cities have signed up for events, rounded up sponsors and put together guest lists. The goal of the event is to raise money and awareness to combat the 1.1 billion people who don’t tweet have clean water to drink. To find out more about the cause visit the charity: water group. Each city is asked to set a goal of at least $4,000 (the price to sponsor a water well in a development area). Check out this page to find out more information.
