Response from Facebook
Facebook is a free service and something that many people find adds value to their day-to-day lives. As with any service, users do need to invest some time in order to use it properly. With the introduction of master sharing controls in May this year Facebook has have made it very simple for users to set all their settings to one option that suits them using one click. With Places, we realise location is a sensitive area so we went even further to help people control their privacy by defaulting sharing to friends only by default – the most conservative of all location services. Users also get clear pop up disclosures and notifications the first time they check in or a friend asks to check them in with a clear ‘learn more’ section, as well as notifications every time they are checked in after they have agree to use the product. We also created simple guides and videos to help educate users on how to use the product as referenced in the original comment.
