Wikiversity, a sibling (why do folks often use the term “sister” instead?) site for Wikipedia, starts its third year today. It doesn’t have as much content as its big sibling, but it’s growing.
Wikiversity was officially launched as an independent site on 15th August, 2006, shortly before 7 in the morning (UTC). Wikiversity had existed as a project within Wikibooks for almost two years prior to this (starting in September 2004).
At its launch, some existing content was moved from Wikibooks. Wikiversity had approximately 370 articles on its foundation date and about 63 contributors who had edited at least 10 times.
