While I'm sure a lot of people are interested, a few questions come to mind...
Personal fitness is a field that requires a certain level of professionalism. It's natural that people will want to know your credentials, which is where the first question comes in: what qualifies you, as a personal trainer?
People have many different body-types and dietary needs, and some have physical ailments that make ordinary exercises difficult. What's your general perspective on health and fitness, and how do you plan to handle these obstacles to training?
There are many different reasons people have for getting in shape, and they can be reflected in their end results. Some want to look good, which is why their diet and exercise are focused on building a specific type of appearance. Some need to build strength or endurance, for the purposes of their jobs. Some need to become more flexible, and some are looking for well-rounded programs that will give them a general edge in fitness over others. For some, it's not even a matter of getting into "fighting shape"; it's more about just getting healthy. What kind of programs do you specialize in?
These are just three of the necessary, and reasonable, questions that a knowledgeable individual will ask, before agreeing to anything. As a fitness advisor, I'm sure you agree that it's a good practice to ask such questions, and get to know such instructors, as well as possible. It eliminates the potential, in the future, for complications and medical issues, and if the client and professional can't fit together in a working relationship, it saves everyone time and investment, so each party involved can find a better fit.
In short, it's a good idea to post any and all relevant information about yourself, on this particular matter.
