I have a group for family members so we can all stay informed of things happening with each other, it's private, only the people I've invited and have accepted can see it. I have a page as well on another topic and with that anyone you are friends with will be able to see all your comments on it.
Both the page and the group show up on MY sidebar, they'll show up on whomever is a member of a group or "likes" a page.
