Facebook puts things in your News Feed that it thinks you are interested in. This can include status updates, photos, videos, links, app activity and likes from friends, pages and groups that you follow on Facebook.
Remember, you can choose to “unfollow” a FB friend, so you don’t see what they had for lunch, but you continue to be their “friend”
Remember, you must have a personal profile/account in order to create pages and/or groups.
