Hundreds of Vancouver Tweeters will be stepping out of cyberspace and meeting face-to-face tomorrow night at Twestival, the world’s largest fundraiser organized through Twitter.

The festival is being held simultaneously in 200 cities around the world, including at the CBC in Vancouver.

Proceeds from the $20 admission go to Concern Worldwide — or @Concern Worldwide — to improve education in developing nations.

Popular Vancouver blogger Rebecca Bollwitt, author of miss604.com, is organizing the event and said social media are powerful tools to bring about social change and spread awareness about charitable campaigns.

“For a very low cost, a non-profit can put one tweet out and that chain reaction gets passed on,” said Bollwitt, who has 10,579 Twitter followers. “Whatever I put on Twitter goes to my followers, and my followers re-Tweet to their followers.”

Bollwitt said people use Facebook and Twitter for more than just status updates, and that social networking will continue to change the way people do business and campaign for causes.

“It joins (people who) use the same tool to communicate but don’t necessarily work within the same circle,” Bollwitt said. “You can sit there on your computer and make a difference with the click of a button.”
