I am interested in using reputation and points systems (like the one used here) to improve how we recognize what people learn and the skills they have. There seems to be a disconnect between the innovation in web application development, where we see lots of experimentation with activity streams, badges, and reputation/ points systems - and the old-fashioned and traditional way of testing knowledge by making learners take, often meaningless, exams.
Is this already happening with stack overflow badges - are users getting jobs by pointing to their badges and points?
If anyone has done research on the topic, please leave a comment and get in touch. We are hosting a workshop on the topic in late September, and we'd love to invite someone who was involved in designing the Stack Overflow points system (or similar systems).
