My likes and comments are not showing up in my newsfeed (after days). The Photos tab is not visible to everyone.
Here are my privacy settings:
Account -> Privacy Settings -> Connecting on Facebook - View Settings -> "See your likes, activities and other connections" = "Everyone"
Account -> Privacy Settings -> Customize Settings -> "Posts by me" "Default setting for posts, including status updates and photos" -> Everyone
Account -> Privacy Settings -> Customize Settings -> "Edit privacy settings for existing photo albums and videos" -> Photo Albus -> Everyone
Newsfeed -> Most Recent -> Edit Options -> All of your friends and pages -> Edit Options -> Hide posts from >
Apps (left hand column of Home page) -> "To control how your friends see your activity, click here" -> Info accessible through your friends -> [Boxes checked] "Bio," "Interested in," "My photos," "My links," "My notes," "Activities, interests, things I like"
(Note that I did not select "status updates" in the Apps setting. Facebook documentation says "status updates" are exclusively that - you used that named function to post an update - it's not likes, comments, photos, etc.)
