I've been whining a bit about the lack of innovation in video conferencing in my RADVISION blog, and even took the time to suggest what the next innovation might be.
At the time of writing these posts, I haven't had the time to read Robert Cringely's post about the education system:
Education, which - along with health care - seems to exist in an alternate economic universe, ought to be subject to the same economic realities as anything else. We should have a marketplace for insight. Take a variety of experts (both professors and lay specialists) and make them available over the Internet by video conference. Each expert charges by the minute with those charges adjusting over time until a real market value is reached. The whole setup would run like iTunes and sessions would be recorded for later review.
