Perhaps another less depressing reason is the intersection of two things: 1) For all its negatives, online culture makes it easier to find and acknowledge different groups with different tastes that share yours, you're not as subject to having to "fit in" just with those near you. Maybe another way to say it is that fewer things are "weird" because it's easy to find others doing something similar 2) The availability of styles is not quite as bottlenecked into a limited number of taste-makers like it used to be.
