Beginning Friday, Facebook is letting its users vote on changes to its privacy policies.

This is the second time the social media company is letting users vote on policy changes, The Associated Press said.  The first time was back in 2009 when Facebook was a much smaller, privately held company with about 200 million users.  Over 1 billion users are on Facebook now.

The vote is about updates the company announced in May, a week before its initial public offering, the AP said.  New sections explaining how Facebook uses people’s information are part of the changes.

As a result, Facebook has the opportunity to start showing people ads on outside websites, targeting the pitches to interests and hobbies that users express on the site.

Facebook said in a blog post Friday that it is reviewing the voting process.
