addition one:
Today I worked on the McLuhan Wiki page. I added a picture of McLuhan which I found using Compfight. The next thing I added was the YouTube video which we were required to watch when we were first introduced to McLuhan. Following the YouTube video I was able to find an outside article which also relates to his idea of the medium is the message. There are links to the original article about Twitter and to the McLuhan The Medium is the Message article as well.
addition two:
My second contribution was on the multitasking page. When I began the page was completely empty but I updated it with links to the Jenkins article along with a little summary of multitasking. I also talked about the possible negative effects of multitasking and included an article and YouTube video as supporting materials.
