An interesting question with even more interesting answers. Because you (and only you) will be able to see who visited your profile in your “My Photos” screen. If you don’t want to appear as a profile visitor you don’t have to do anything because the new feature’s standard setting is set to “disabled”. Only you can enable the feature by clicking the according check box within the menu “Membership / Privacy options / save profile visits”.

Enjoy the new feature and get in contact with your visitors …
