1. Visit a website that interests you. Print the homepage or one other pertinent page from the site. Write a one page summary of the site that addresses the following topics:
- What is the URL of the site?
- What is the purpose of the site?
- Who is the intended audience?
- Do you think that the site reaches its intended audience? Why or why not?
- Does this site appeal to you? Why or why not? Consider the colors,images,multimedia,organization,and ease of navigation.
- Would you encourage others to visit this site? Why or why not?
- How could this site be improved?
The website that I chose was Facebook (https://www.facebook.com/?ref=tn_tnmn). The main purpose of Facebook’s site is to connect with family,friends,colleagues, etc. via long-distance communication. The intended audience is both male & females between the ages of 13-85. Is this site useful to me? yes. I say yes due to the fact that Facebook has made it much easier for me to keep up with all of my family and friends,but also helps me to stay in touch with my colleagues & helps keep me up to date on my schoolwork. I do believe that this site does reach the intended audience due to the fact that facebook makes it easy to use all of the applications that they provide on their site. I also believe that it does reach the intended audience because they provide all applications to various audiences as well. I would definitely encourage others to visit and sign up for Facebook because of all the benefits that Facebook provides for both the young & the old. Although there are many benefits to Facebook, the site does have its drawbacks. Even though there are many great applications & services that Facebook provides, they tend to have “glitches” every once in a while that can be improved on more. I also dislike how the report process when wrongdoing is done. Sometimes Facebook allows wrongdoing to go so far that it literally has to “hit the fan” before Facebook takes action. Granted, they have been making improvements to make Facebook a more safer and friendly social website, but they still are rough around the edges.
