In Johnson's discussion of intelligent agents he tries to show both the advantages and disadvantages to using intelligent agents. This debate leads to an understanding of how at first one may see benefits to intelligent agents. They can record a person's likes and dislikes. The agent can then make an educated guess on what else the person may like by comparing this person's likes and dislikes to a database of another people's likes and dislikes and find similarities. This process is used in many websites today including Amazon.com.
Amazon.com records selections that are made when visiting the site. Then takes the results, and spits back a list of other products that may interest the individual. Comparing the results to everyone who has visited before. This idea of recommendations by using an intelligent agent is great for Amazon.com because they can influence someone to buy other products that a person may want before they realized they wanted them. In my particular case I found that, as Johnson referred to in his book, most of the recommendations that were made were recommendations that are comparable to suggesting The Beatles album "Sergeant Peppers Lonely Hearts Club Band". This means that the agent is working but continues to return items that everyone knows they like already.
On the other hand when visiting my Yahoo I found that after making the different choices, to set up my account, the result was pleasing. In the first column I picked e- mail notification, the ticker bar and the weather bar. In the second column I chose the general news, technology news and a few comics strips. Next I read a few articles that grabbed my attention. While on my Yahoo I saw I had a new e-mail and how much my stocks had gained. When comparing this service to the television I felt that it was much more specified to my taste and liking opposed to the news on television. The advantage to the newspaper over my Yahoo was the depth of the articles.
