I don't specifically "mind map" and tend to take more outline-ish structured notes, but then as different things are discussed, or something harkens back to something mentioned earlier, I get scrawl in the margins, arrows pointing back and forth, etc. I just write down the connections I make while I'm listening to things, without really trying to. I suppose that has a lot of similarities with mind maps. Some subjects have more arrows and lend themselves well to that. Others essentially remain in pure outline formats. There's no one true way to do these things.
