Do not be a fusspot and say that online petitions do not actually have an impact.
On November 1, Change.org announced their victory over Bank of America’s $5 debit card fee after over 300,000 people signed a (online) petition asking the bank to eliminate the fee for all customers. The petition was created by an independent member of Change.org who also broadcasted her plea onto Facebook and Twitter. Dominitz says that Change.org depends on social networking sites so that people can use their connections to spread word of their cause with immediacy. He believes that online petitioning is a tool that goes hand in hand with why people reach out to one another online on sites like Facebook. “It’s looking for something that is larger than ourselves—making or signing a petition gives you a sense of being part of your world.”
So yes. They have worked.
