Facebook. For some of us Facebook is just two four-letter words, for others it is the local café, and for others still it has replaced letter writing and postal stamp buying. Regardless of our personal feelings about it, like the telephone – (remember that black thing that sat in the hallway nook tethering us to within 3 feet of the wall) – Facebook is here to stay. And like the telephone, just when we finally figured out how to friend our friends, post on our wall, leave comments on our friend’s wall, what does Facebook do? . . . It changes!
