Chris Nolan's presentation was interesting and covered a lot of material that many people do not consider too closely even though they are exposed to it everyday. The first was his explanation of google's search algorithms to determine which sites are first on their shown results for a search. Most people use google everyday and just expect the best results to appear without putting much thought into why those sites were chosen. He also explained how easily people can miscontrue some webpage they see because of how the page appears legitimate in its set up. The cleancoal example he showed us was a good example of a page that served as a spoof page by appearing to endorse coal as an alternative form of energy. The presentation overall answered some questions people may have about the internet and how to properly use it.
