> I'm super curious--how often do you actually use the menu and what do you use it for?

I use the menu really frequently -- for pretty much anything that isn't a toolbar button.

I tend not to use keyboard shortcuts generally, but particularly if I'm just reading a website -- in that situation, my hands are on the mouse, not the keyboard, and moving to the keyboard to type a shortcut is more inconvenient than just being able to use two clicks on a menu.
