Nick: I believe this is a follow-on to the platform that Apple designed to deliver courseware through the iPad called "iBook Author": http://www.apple.com/education/ibooks-textbooks/ http://www.apple.com/apps/itunes-u/ http://www.edxonline.org/about.html The key point is that reputable educational institutions are developing a lot of online content that will be subject to peer review, evaluation and validation. People will get academic recognition for their work. This is very different from anonymous crowd-sourcing of content. So, if a faculty member or graduate student has the opportunity to work on content using iBook Author/edX vs working on content using MediaWiki/Wikipedia, I suspect that there will be heavy incentives toward the former. Also iBook Author has a friendlier WYSIWYG user interface than MediaWiki. We should still try to recruit campus ambassadors, but we must recognize that we face tough competition. However, the idealistic desire to share knowledge and the competition between dissemination systems has been around for a long time. That is why I started writing lessons on the PLATO system back in the 1970s. The market will decide whether people will share knowledge on MediaWiki or some other platform. --Bob Quoting Nicholas Michael Bashour <nicholasbashour(a)gmail.com>om>:
