Today, Wikipedia is home to 43 million articles in 285 languages and all of these articles are written and edited by an autonomous group of international volunteers. Although the non-profit Wikimedia Foundation diligently keeps track of how editors and users interact with the site, until recently it was unclear how content production on Wikipedia was distributed among editors. 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.
