When we publised our insight report on "50 ideas for free e-learning" a few months ago, we got a lot of reactions. One in particular caught our eye. David McKnight is CEO of Omnipress, a US company that specialises in print publications to support training events and conferences. He felt we had missed one of the most obvious and effective low-cost training devices: print.

He challenged us to explain why e-learning was better than either print or face to face. We like a challenge, so David, Mark and Stephen got around the skype table to thrash it out.
