MIT’s Sociable Media Group looks like an interesting bunch of people. I like the Webbed Footnotes project, where one can “annotate web pages with comments and can read and reply to the annotations left by others.”
I think the existence of groups just like this one suggest a course of action for EdLab’s software development activities: sharing our code. A downside may be that it takes more time to write code that is suitable for sharing, but a benefit would be that if a project gets some legs, we could benefit from collaboration from outside our small development group. There seems to be momentum in this direction, and it could be a great way to compete in the educational software market in the near future.
