"EdX will release its learning platform as open-source software so it can be used by other universities and organizations that wish to host the platform themselves. Because the learning technology will be available as open-source software, other universities and individuals will be able to help edX improve and add features to the technology."

Is anyone else worried that this'll be a one-sided "we released the damn source in a zip file" style open source? When administration has such a big stake in a project like this, I hope they will allow community style open source. It's harder to justify each design decision you make to a bunch of whining disagreeing third parties on a mailing list, but ultimately I think it's for the best.
