I think if you are going to capitalize the 'P' in professional you need to be a member of a regulated body that performs peer review, has a code of ethics, practice standards, requires professional liability insurance, etc.
That doesn't mean lots of people aren't professional in their dealings with the public, how they act in various roles in their jobs or are in general honest and capable.
Not just anyone who hangs out a sign is a Professional - talk to the lawyers, doctors, etc of this world.
If we accept that everyone who merely 'earns the majority of their income' in GIS is 'Professional' then we doom ourselves to the back office with a definite income cap, limited control over our future and very little say in how the data that we manage and are experts in is used.
I'm just curious as to what the term means exactly.
