Facebook, an online social-networking website, is asking its 175 million members for input as it revamps its terms of use agreement.

Founder and CEO Mark Zuckerberg made the announcement following a backlash over controversial changes to Facebook's policies last week.

"The purpose of Facebook is to make the world more open and transparent by giving people the power to share information," Zuckerberg said in a conference call with reporters. "We really took last week as a strong signal about how people cared about Facebook and wanted to be involved in helping to govern it."

Facebook members will be allowed to comment on any proposed changes to a set of "Facebook Principles" and a separate "Statement of Rights and Responsibilities," both issued Thursday. Virtual Town Halls will enable users to give feedback until March 29. In addition, the company may put any subsequent changes up for vote that will be binding if more than 30 percent of active registered members cast a ballot.
