I think you're on the right track here, but I would go a step further.
Asking a question and listening is a good approach. But it's important to keep in mind why you are asking.
Networking shouldn't just be about potential business. It should be about connection.
Asking the question "What do you do" is a fine appetizer. But the meal really begins with the next question.
"What is your favorite thing about what you do?" or "How did you get you get into that?" or "Who are your biggest influences?"
These kinds of questions allow us to discover how interesting people realy are, and quickly open the possibility of genuine rapport.
This very simple augmentation creates conversation that stands out and is meaningful. It also builds community.
And that is smart business.
