On 15 January 2021, the popular online encyclopedia Wikipedia marked its 20th birthday.
Since being launched back in 2001 by Jimmy Wales and Larry Sanger, the website has accumulated millions of articles in dozens of languages (with the English version alone featuring over 6,229,000) compiled by thousands of editors from all over the world.
The name of the project, coined by Sanger, is a portmanteau of Hawaiian word wiki (meaning quick) and encyclopedia.
This anniversary did not go unnoticed on social media, with many wishing the site many happy returns.
Despite all of Wikipedia's pros, however, the very concept of the free encyclopedia presents a potential problem, as it can be edited by anyone, anytime, which means that certain information added to it may be unreliable, at least until the necessary corrections are made.
