Does the MBBS degree receive this much attention? I'm being facetious...
Anyways, there are a lot of good points here. I think the biggest differentiation between DO and MD (on a professional level) is the regulatory board exams and licensure. I think a big step that has been taken recently is the melding of the residency programs. This a very good thing, again on a professional level.

From the patient and general public stand point... I really think that there needs to be more educating the public on the DO practices and what we are. Honestly, I think that should come from the medical schools themselves. Maybe a community project for 1st years. One of the big reasons why I applied so heavily to DO schools and accepted a DO school was the fact that I respect the philosophy of the DO. Meaning that I think that MD's can be overly eager to prescribe chemistry and treat things aggressively with interventions (disclaimer: In most cases, that is the correct path). Yet, I do feel that MD's don't try to utilize less invasive and less chemically oriented approaches to care of more minor things. "Oh, you have a cold... let's put you on this, this, and this... even though it's a virus and really I'm only treating your symptoms. You have high blood pressure, well let's see what kind of medicine we can dig up for you instead of me telling you to go out and exercise and decrease your salt intake. Your you have headaches... well maybe we should stent that 2 mmHg gradient lesion of your IJ..." True story.
I get what serenade is saying, but I don't think we should give up the DO. You are going to find it very confusing when you get into a hospital setting and trying to figure out the differences btw all the specialties and what they do differently from one another and how similar some of them practice, but their patients know. For example: critical care intensivist, critical care surg, critical care pulmonology, and critical care anesthesiology... in the CCU, ICU, MICU, SICU, etc... there is no distinction. Maybe that's not the best way to describe it, but I hope you can follow.
