Facebook will be changing its privacy settings to give users more control over the amount of information they share and who has access to it. Although the company was tight-lipped, apparently users will be able to share personal information with the general public. Charlene Lim, founder of digital strategy firm Altimeter Group, says that the proposed changes could give Facebook a competitive edge over it’s rivals. “In many ways,” she says, “it trumps what Twitter does because there are two levels at which someone can use Facebook — a ‘public’ one versus multiple layers of ‘private’ feeds.”
