yup they are lol i put different words in the search and then clicked the posts by everyone tab. and its like a constant feed of people who are using the word and/or words i searched for. this includes movies pictures music and so on. any type of post will show up (links, status updates, wall posts, and notes). and it does not matter how private your facebook is. i tested it and still i found my posts showing up both on the pages and in the posts by everyone
