Love this, I have the same view. I use them for search in cases where I have to circumlocute and can't quite say what I mean (I found an old book I could only remember very vague broad strokes about this way when no search engine could do it) and for "framework" questions, e.g. what is this about and how do the pieces relate, which I would go so far to say is another type of search problem (it's search where I'm starting from zero). I still have to take it with a grain of salt but to your point it's enough to familiarize me with "landmarks" in the information space and then to start building more solid understanding from that foundation.
