wikiHow
wikiHow is a crowdsourced online platform founded on January 15, 2005, by entrepreneur Jack Herrick, which provides free, step-by-step instructional articles on a broad array of topics, from everyday tasks to specialized skills.[1] Designed as a collaborative wiki, it enables volunteers worldwide to contribute, edit, and refine content through a process involving research, expert input, and community review to ensure practical utility.[2] The site's mission is to empower every person on the planet to learn how to do anything by creating the world's most helpful instructions.[3] With over 230,000 articles generated by thousands of contributors and subjected to ongoing audits based on user feedback, wikiHow serves more than 150 million monthly visitors across 230 countries, positioning it as a major resource for self-directed learning.[4][5] Key features include detailed, illustrated guides often vetted by domain experts, fostering accessibility for users lacking formal education or resources.[2] However, as a volunteer-driven endeavor, it has drawn criticism for variable content quality and instances of guides on questionable or potentially harmful practices, such as achieving an unrealistic "thigh gap," highlighting inherent challenges in scaling crowdsourced knowledge without uniform oversight.[6]
