Who's afraid of Wikipedia? According to the New York Times, women are.
The Wikimedia Foundation, the organization that runs Wikipedia, collaborated on a study of Wikipedia’s contributor base and discovered that it was barely thirteen-percent women; the average age of a contributor was in the mid-twenties, according to the study by a joint center of the United Nations University and Maastricht University.
Because I know you're wondering, United Nations University is in Tokyo and has a killer football team. Anyway, Wikimedia is striving to close the gender gap. “Everyone brings their crumb of information to the table,” said Executive Director Sue Gardner. “If they are not at the table, we don’t benefit from their crumb.”
So which crumbs are missing? Examples trotted out include an entry for a noted female British author, which was five times shorter than the entry for a fictional man from the video game Grand Theft Auto IV; episode summaries for Sex and the City, which are less comprehensive that those of The Sopranos; and "friendship bracelet," which has fewer paragraphs than "baseball card."
The prevailing wisdom is that "Wikipedia is experiencing the same problems of the offline world, where women are less willing to assert their opinions in public." So ladies, stop weaving that friendship bracelet and start contributing to Wikipedia. The internet needs you.
