Bottom lower left, but I keep it hidden. Also, since I use path finder, making the Dock's trash useless, I have some quicksilver mouse triggers in the corner to move dragged objects to the trash, eject disks, and open the trash when I click the lower left corner.

Ack. That should be bottom pinned right, and quicksilver actions on the bottom **right** corner. Silly me.

Also, the only items that are permanently there are path finder, quicksilver, and the terminal. I took the regular finder icon out of the dock with TransparentDock (which I don't use for anything else, oddly). I'm not exactly sure how they take the finder out of the dock, but it's great.

Quicksilver handles most everything, while occasionally I drag documents to application icons in the dock, especially when they are of types that an application hasn't declared for itself, and so they won't use that app. in Quicksilver.
