Flickr.com and youtube.com are also a part of our lives, at least for the moment as a part of this class. We're displaying ourselves through images and videos, and commenting on each others' work. If it became a habit to use these websites for ourselves and our friends, we could communicate here also. Of course, Facebook does images and videos also.
Most recently there's GoogleEarth and although we didn't adventure into saving our information on GoogleEarth to retrieve from anywhere at any time, it can be done and we can "communicate" again with others this time focusing on maps and locations on the earth, push-pins and balloons with our personal notes.
Where will this end? Or will it?
