@matigo Chickens and crazed geo-location are attributes that few posts will have. Chicken is a specific "kind" of WP post. It just demonstrates that you can add anything to the WP "kind" taxonomy (which lays on top of and doesn't map to WP's core Post Format). If you store the Kind, you can store Chickens, or Exercises, or Reading or whatever. Do you have to decide in advance? It's just an object.
