Twitter has the capacity to ignite revolutions and enable small acts of kindness, but there's also a darker side to the microblogging network.
Floating Sheep, a group of geography academics, created the "Geography of Hate," which maps racist, homophobic and ableist tweets in the U.S. After searching for all geotagged tweets in North America between June 2012 and April 2013, students at Humboldt State University manually read and coded the sentiment of each tweet to determine if a specific word was used in a positive, negative or neutral way. In a blog post, Floating Sheep cited "dyke" as an example: While the word is a homophobic slur against lesbian people, it can also be used positively (e.g. "dykes on bikes #SFPride). Mashable.com
