Maybe, I didn't really feel motivated enough last week.
Concerning the organisation, one realize that behind an esay to use tool ((Media)wiki) there is a considerable organisation to get structured content. My own experience helped me to realize that this organistion in slightly diffreent between the different projects depending on people involved, their own priorities and level of structuration.
The other axis is organisation of content which is quite clear in an educational view :
- wikipedia, wiktionary, wikiquote for "basic", extended, NPOV knowledge
- wikimediacommons as repository for medias content used in other projects
- wikibooks as organisation of knowledge in a progressive, organised, pedagogical manner
- wikiversity handle more dynamic content as it concerns organisation of learning : definition of course and real course hosting (as OER course).
Concerning impact, I think we all are convinced that this movement will help to increase access to culture, information and knowledge. We also hope tht it will get comparable impact than libre software to software industry.
Will wikimedia be one of the organisations to foster this impact ? For the encyclopedy level, we're now sure. At teaching/learning level, there is still work to do, but experimentations like OER course will definitely constitute valuable experience for the future of Open Knowledge.
