A map that aggregates geo-coded tweets shows the location of racist and homophobic comments. The map was put together by a team of geographers lead by Dr. Matthew Zook of University of Kentucky, who called themselves Floating Sheep. Floating sheep has has built maps in the past by pulling together user-generated, geo-coded information from the Internet. They've explored, for example, The Price of Weed, and compared the use of the word "beer" vs. "church."
The results demonstrate markedly different regional preferences and word choices. For the team's latest map, Geography of Hate, they searched for all geo-tagged tweets in North America between June 2012 and April 2013 that contained racial and homophobic slurs.
