I keep reading this same concept and I keep questioning whether they have the whole story. I'm definitely in the group where cracking gives temporarily increased mobility, but it's more than that. A joint which is bothering me will most likely feel better if cracked and this can be the difference between very painful to walk, then my knee cracked, instantly the pain was gone. And usually, a joint which is actively being used will not crack--but if my knees are complaining about a downhill stretch they will feel a lot better if I can crack them. Also, I can sometimes feel a difference in how a joint moves. It just feels smoother when cracked. I don't understand it but I've wondered if it was somehow tiny bubbles (think cavitation) that don't form if the gas was removed by a crack.
