Exactly.

I hadn't thought about this, but it's clearly true. Except I think it's the opposite. The earth is spinning faster because some of its mass moved closer to the center of the earth (like when you're on a spinning stool and pull your arms in so you spin faster). Since the mass is closer to the center of the earth, it's farther from the surface, which means gravitational force at the surface of the earth which diminishes as r-squared, should be less than it was. Maybe there's an asymmetry effect because it happened in one spot rather than equally distributed around the whole sphere, but I still think it should end up being less.
Heh, wireless owns btw. I'm sitting in my car in a gas station parking lot waiting for a state inspection, who'd have guessed there was a wireless network here? Actually, it sees four of them, but I just connected through the first one it found  This isn't even in the city, it's a little town. |

The Earth has the same mass.

There are at least four super win things about this sentence.
