The blog, Science and Sensibility (Lamaze International’s “Research Blog About Healthy Pregnancy, Birth & Beyond”), picked it up and asked to run it since it's very topical right now, what with the recent important study on Practice Variation.
I revised my very-quick original post and expanded on a few points, added some new research, reformatted it a bit, and generally prettified it up. (I spent all my time on that, so no new post here till next week.)
In the meantime, the revised post is now up on Science and Sensibility. You can go and read it here.
