Again, the last two responses are clearly proving my point and why again I think the original blog post is not a bad idea; this belief, by what appears many, that what professionals of other industries say has to be completely dumbed down because it is just too difficult to grasp by 'clients' is an attitude which I don't live by (yes less is often more in marketing but you have to know your clients). I haven't always been a photographer. I have family member that are doctors. I have written and sold software that prices exotic fixed income and equity derivatives, built extremely complex programs for Actuaries to value pension plans and for Portfolio Managers, who I was one for a long time, to value companies using many different methods.
Your opinion is interesting, and I don't really want to comment on the original blog post. It is hard to imagine me as a person who doesn't know the jargon talking to a photographer. That being said, your opinion does have a significant exception. If I spoke to a patient or patient's family using the same language that I use to talk to a physician then I would never get my point across and would be doing a disservice to the patient. I am not treating them like morons, I am using language that they already understand. Medicine uses a lot of precise words that are important when talking to each other and totally pointless when talking to a patient. This is why I also start every conversation I have with my family's doctors by telling them that I speak the lingo. I can use all the medical terminology I want when I talk to patients, but usually it only serves to confuse them and make me sound smart. The fact that you have family members that are doctors doesn't necessarily mean that you will be able to "talk the talk."
