Twestival® (or Twitter Festival) uses social media for social good by connecting communities offline on a single day to highlight a great cause and have a fun event. Twestival is the largest global grassroots social media fund-raising initiative to date. Since 2009, volunteers have raised close to $1.2 million for 137 nonprofits. All local events are organized 100% by volunteers and 100% of all ticket sales and donations go direct to projects.
