From a report on Motherboard: According to the results of a recent study that looked at the 250 million edits made on Wikipedia during its first ten years, only about 1 percent of Wikipedia's editors have generated 77 percent of the site's content. "Wikipedia is both an organization and a social movement," Sorin Matei, the director of the Purdue University Data Storytelling Network and lead author of the study, told me on the phone. "The assumption is that it's a creation of the crowd, but this couldn't be further from the truth. Wikipedia wouldn't have been possible without a dedicated leadership." At the time of writing, there are roughly 132,000 registered editors who have been active on Wikipedia in the last month (there are also an unknown number of unregistered Wikipedians who contribute to the site). So statistically speaking, only about 1,300 people are creating over three-quarters of the 600 new articles posted to Wikipedia every day.
