I have a confession. I like Pokémon.
It'd really be more accurate to say I never stopped liking it. Sure, there was that point when it wasn't "cool" anymore and I was too busy trying to be "cool," but this is the kind of thing that just sticks with me. So, naturally, I've built up a collection of Pokémon cards. And what does someone like me do when they have a collection of something?
Build a WordPress-based database site for cataloging it, of course! This is where hashing a custom taxonomy comes into the picture.
