The "just ask" approach is very tricky. It does not emphasize a critical element : Most people love to rant and complain about things that annoy or bother them. People rarely if ever get to ideas to solve problems or even to describing the underlying problem.

That's your job. Develop hypotheses about what the underlying problem is and ask them questions to try to falsify them. Develop hypotheses about solutions and build mockups or proofs-of-concept and have them try them out to falsify them.
No one will hand you a business idea on a platter. But problems to solve are the easiest thing to find in the world.
The question I was answering was: "How do you guys network with the right business people to speak their language and find out how their processes work?"
I don't think "just ask" is misleading at all. The fact that most people will happily complain about their business processes but won't have ideas to solve them doesn't make it "tricky", it makes it an opportunity.
There might be fields of endeavor where identifying solvable problems is incredibly hard, maybe in academia or politics, but business processes? Execution and, if you want to get rich, scaling up are hard. But identifying solvable problems with people's business processes is totally one of the "easiest [things] in the world".
