Hi Matt,

to be honest, I struggle with literature...over 10 years old (your second link) I mean how relevant is it for 2014?

Things move on-do they not? Otherwise, why are we not still using Morse Code-perfect mode for communication in my view

And...with regard to research/as opposed to literature (there is a difference) the stats in this 6-year old study:

sound convincing-but we are all not running out to get Web CT at the mo-now are we?   

Cheers,

Dawn
