Some people get their kicks from roaming around in the great outdoors.
They love the open space, the feeling of having the entire picture spread out before them. Me, I love to walk through the streets of a city, taking a turn here, a side street there, guessing at where I'm going to end up. Please, don't give me a map, it ruins the feel of being inside, of being a part of the labyrinth. When I read, it's much the same. Hypertext allows me to get lost in my reading in much the same way as wandering around a city does.
