Not at all, I fear. A primitive bit of technology but a sophisticated business model that might well work if the technology offered more. The crossover between open and closed approaches is potentially very powerful. But, as far as I can tell from a fairly cursory exploration, sadly this potential innovation seems to reinforce the wrong values and pedagogies like all the rest and seems sub-moodle in functionality. Sigh.
