Még nem volt időm végignézni, de hátha érdekes: http://www.youtube.com/watch?v=-6eHyShpws8 Google Tech Talk (more info below) August 25, 2011 Presented by Erik Moeller, VP of Engineering & Product Rob Lanphier, Director of Platform Engineering Alolita Sharma, Director of Features Engineering ABSTRACT Wikipedia is the most comprehensive encyclopedia ever created, a result of the collaboration of hundreds of thousands of people. It's operated by the Wikimedia Foundation, a non-profit. Learn more about some of the latest developments in wiki technology: a new editing interface for Wikipedia; social features that support collaboration; a new labs and application development infrastructure for volunteers; improved media support; developments in structured data, and more. Wikimedia's tech projects are 100% open source, and we're hoping Google and Wikimedia can learn from each other.
