Last month I received an invitation to join a Facebook group called “Breast Cancer Awareness Week.” The purpose of this group was to inform university students about the many events that the Emily Taylor Women’s Resource Center on campus was sponsoring from Saturday, September 29 to Sunday, October 7 – events including a softball tournament, a survivor’s panel, and a 5k run and walk. I joined this group not only because I was a member of the Breast Cancer Awareness Week committee but also because I fully believe in and support the social good that the group was promoting – an end to a disease that one in eight women will be diagnosed with in their lifetime. The group effectively presented its message by detailing the week’s events, creating a link where those interested could sign up for the 5k run and walk, and posting videos that were interesting to viewers. The group also used the tool of mass messaging to remind group members about each day’s events and to encourage group members to invite other friends to join the group and, ultimately, join in on the cause. The group was very effective in its efforts to inform and promote, and even two weeks after Breast Cancer Awareness Week has ended, the group still boasts 151 members today. The “Breast Cancer Awareness Week” Facebook group is a good example of how a social networking tool such as Facebook can be used to advance a good cause and to promote activism among a large group of people.
