I recently joined this group so am still figuring what we're all about. Jay said that many of you might be interested in this paper a co-researcher and I recently wrote on our experience building/using a free-form social learning platform for the Information Systems department at BYU.
I love to answer questions, get feedback, and hear your experiences building / using similar learning technologies.
The paper is a pre-final copy so be warned.
Thanks,
