Sometimes it is hard to start a topic and sometimes it is hard to add new information to a topic that already contains so much information. I signed up to be a contributor on the page call “How Business is Using Social Networking” of our class wiki. There already contain so much information. I can’t think of anything new. Therefore, I just edited on others works. However, I did add a paragraph about the relationship between mobile phone users and business world under the subtitle “Cellular Social Networking.” I will continue adding new information to the page when I find something relates to it.
