MANILA, Philippines- Social media like Facebook and Twitter had changed the way people access information.

?I would like to believe that the open exchange of information can create a positive global impact,? said Twitter?s co-founder Biz Stone during the recent Youth Engagement Summit 2009 in Kuala Lumpur, Malaysia.

Stone cited that some protests and rallies were organized through Twitter.

?Tiny bits of information can have a profound impact like bringing people together on the streets for their cause,? said Stone, who started the company along with Jack Dorsey and Evan Williams in 2006.

?We started Twitter with the idea of people sending SMS of what they?re doing because the potential for impact increases with a focus on mobile,? added Stone, who noted billions of mobile phone users.

According to Stone, Twitter users now are thinking more succinctly and are connecting relevant links to their tweets.

?We want people to think that Twitter is about the triumph of humanity, not the triumph of technology,? said Stone.

Meanwhile, Facebook?s marketing director Randi Zuckerberg, likewise, mentioned that Facebook became an instrument of change as it was used in the campaign of US president Barack Obama, America?s first African-American president.

?We?re glad that a lot of applications such as causes, games, and entrepreneurship had been opened through Facebook,? said Zuckerberg.

?In social networking, execution of the product is what matters to be successful. We also take our consumers? feedback very seriously,? added Zuckerberg.

Zuckerberg also recognized how misinformation can be proliferated through social networking sites. She cited an example such as the balloon boy hoax, which spread in Facebook and created panic in the US.

?There?s so much noise online today and expert opinion is more important now than ever,? said Zuckerberg, adding, ?Facebook is always coordinating with government agencies, media companies, and experts whenever global issues such as the influenza A(H1N1) virus arise.?

?Sometimes getting accurate information is difficult not only on Facebook but everywhere. So we?re definitely trying to do our part to make sure that accurate information is being delivered,? she said.
