I'm probably one of those people who waxes lyrical about bookstores but don't really find myself in them nowadays. To me it's a special experience tho. I experience them like museums and there are very few left (!!) that are imbued with that character of poetic chaos and serendipity. The only book shops left may indeed only be frequented by the demographics that keep the margins nice and fat. So I suppose there's a hidden bias in your observation.
