I have tried to read other authors and other genres lately, simply because I realized that my world-view was too narrow and wanted to see the world through other people's eyes. For the most part, I prefer those new reads over the old ones. So yes, my tastes have evolved.

(And, for what it's worth, evolve means changing to be more suitable for the environment. The idea of evolution being progress is purely a pop-culture notion that no serious scientist would take seriously.)
