I lower my blade after every use. I also unplug my saw after every use. I’d like to say it is because of my acute safety sense, or some sense of self-preservation, but in reality it is because I use the top of my saw as a work surface because it is my only true flat surface. I put a piece of plywood on top and use it as an assembly/work area. My shop is 15X30, and I can’t leave the saw in the middle of the room, so I have to move it out of the way after use. So I do those things for practical reasons other than safety.
