I really like this idea: Small Pieces Loosely Joined "What we are trying to demonstrate is the power of using a discrete series of "small" often free/open source technologies in a loosely coupled fashioned, for use in education."
Comment: This view of educational technology is much more palatable (to me at least!) than locked down "do-it-our-way" LMS'. If innovation is a function of variety and diversity, loosely connected tools will afford the greatest benefit to educators and learners.
