100%. We've had a few brainstorming sessions, particularly when coming up with new product ideas or features (aside from those customers requested), and while it isn't often that the outlandish idea makes it, sometimes, just sometimes, it does; and sometimes that outlandish idea becomes the most successful part of the company. I've seen it happen at least 3 times. In my opinion, it's one of the few ways to avoid constantly iterating and truly produce something exceptional.
