I agree with these guys. What you are waiting for is the water in the wood to evaporate out. A stick of wood is not much more than a bundle of straws. Water moves up and down the straws to the ends, not through the sides. Cut them into short lengths and it has less distance to travel. Put a stick of green wood on a fire and water bubbles out the ends, not through the sides.
If it dries too fast, it shrinks and cracks (checks). That will ruin lumber, so they paint the ends of logs with latex paint, but still send them to the sawmill green. They are then stickered (stacked with sticks between them) for air to get in and circulate. In this case, they are forcing the water to evaporate through the sides instead of the ends. This is a long, slow process. A kiln speeds that up, but taken too far, they will dry too fast and check.
But checking and cracking doesn't matter with firewood or smoking chunks.
This stuff was cut a little over a month ago but the short pieces are now dry enough to use:
