"MOOC is a hot topic, I also have written various articles in a relatively short amount of time due to the many developments and challenges going on.
... The latest news is that a core element of EdX MOOC software is going open source. What does this mean for the market?
EdX announced last week it was releasing the source code to its XBlock software on GitHub under the Affero General Public License, a GPL variant designed for network server software. This is a first step toward open sourcing the entire edX software platform." from source: http://www.intelligenthq.com/
