Sylvia R's comment: "I've been a proponent of open content / open learning for a long time now. I'd like to hear what other educators think of collaborative development of learning materials, sharing of content, quality of product... I'd also like to have a dialogue with anyone who has been actively producing, sharing or teaching in this environment."
In Alberta, eCampusAlberta (eCA) is probably the best model of province-wide sharing.
Just a guess....outside of eCA, I'll bet there's not a lot of formal sharing between institutions (or even between deaprtments in the same institution).
Such a shame.
