"Search is the most-used aggregation method for finding science-related information. Pew Internet asked about research in three topics: stem cell research, global warming, and the origin of life. With all three groups combined, about 90 percent of respondents said they route their queries through search engines. Individually, searches beginning at search engines amounted to 87 percent of stem cell research queries; 93 percent of global warming queries; and 91 percent of origin of life queries."

Often times, people will know where they want to go, say its Discovery.com, but instead of going to bookmarks, they go to the search engine. The search engine functions as a notepad that tells them how to get there instead of driving someone to some unplanned destination
