Mark Oehlert and Karl Kapp are having a badly needed conversation between a practitioner (Mark) and an academic (Karl) within the blog comments for Mark's post If You Believe It's Broken - How Do You Change Our Industry/Models/etc.
Read the comments from bottom to top.
Personally, I've noticed that our little corner of the blogosphere makes these conversations much easier. Practitioners get new models and ideas to develop learning. Academics get a better understanding of their models in practice.
I think we've been missing the feedback loop.
