What are "Stephen's shared items?"

In Google Reader, when I read a post, or see a photograph that I want to share there is an option to share it. I added a section in the course web log to share those items. It works pretty well. I can either go to the web log and post to the web log, or if appropriate just click on the share button within Google Reader. The purpose of all this "sharing" is that one of the motivations to take photographs is to have people see them. In the old days you had to think about showing at a gallery or art show and maybe getting a book published. All these internet tools have completely changed the possibilities of sharing your photographs. It is an amazing time!
