There are people like me who are content to throw a burger or a piece of steak on the grill and hope we don't scorch it to death. As long as it's cooked to a point where no one's gonna get sick, and it hasn't been turned into shoe leather, we're happy.
Then there are folks who have taken grilling to a level of passion that calls for commitment, time, and self-improvement to the point that they argue over what size smoke ring is really best for each type or cut of meat; what kind of wood gives a better smoke; what kind of BBQ is really best for chicken... the list goes on and on.
Both of us are perfectly okay with our state, and if I choose to learn more about grilling so I can do a "better" or more "professional" job of it, I have places to go where I can do just that. And the pros will offer advice, solicited or not (because, after all, I have come to a place about grilling), to help me do a "better" job... but will also let me do my thing if that's my desire.
Do I need to draw the analogy out further, or do you catch my drift?
