On the contrary it's slowing down.

Well lets begin by saying "why does it not slow down?". Earth does not slow because space has no friction and earth works off of two forces called "inertia" and "momentum". If I were to throw a ball into space that initial force of my hand pushing it will be all it needs to fly on virtually forever and momentum is what keeps it going until other forces act on it. Why does earth not speed up? Well like I said, there is no other force causing it to speed up. Like with the ball, the ball will maintain the exact same speed until something were to cause it to move faster, like another push, if someone came up with a baseball bat while it was floating through space and gave it a good hit the ball would speed up, and it would not slow down until something were to stop it, such as a brick wall or my hand for instance. Dont listen to these other people, earth is not slowing down, I assure you. Now the moon is moving further away from the earth, VERY slowly, like less than an inch a year and considering the amount of space between the moon and earth that is almost nothing. The fact that the moon is moving away shouldnt affect earths rotation anyhow. And if it does, the earth will not come to a complete stop. The principle of conservation of momentum states that the total amount of momentum of all the things in the universe will never change. One of the consequences of this is that the center of mass of any system of objects will always continue with the same velocity unless acted on by a force outside the system. Once again momentum also refers to outside forces acting upon an object. Momentum plays a HUGE roll in earths rotation, you should look into it. Shuman Resonance has NOTHING to do with earths rotation. "because it wobbles from having all the fat people in America" This has nothing to do with anything, matter cannot be created nor destroyed, it can only change forms. With that said everybody on the planet could gain 200 pounds and that wont change ANYTHING about the earths orbit or rotation.

When Earth first formed, it rotated once on its axis about every 20 hours. After the moon formed, Earth's rotation began to slow down to the 23 hours and 56 minutes it is now. The gravitational pull of the moon has caused the Earth to slow down.

The simple answer is Newtons second law. An object in motion tends to stay in motion unless acted on by an external force.
The earth is spinning and there is nothing slowing it down or speeding it up.
There is no force that is affecting its spin (yea yea... the moon... it is not a big enouph force for us to care right now)
Thus it is an object in motion, and it will stay in motion. Its speed does not change.

there's stability in everything that is in the universe-even in chaos there is some symmetry and some conditions are fulfilled.
the basic pattern in the universe is to rotate and revolve-look at anything that is moving in this universe and you will notice this. this rotation is there until there is enough energy. when energy peters out, the body slows down and begins to be pulled towards its centre of gravity and then stops- if it's subatomic it merges in the dark matter of the universe. if it's macroatomic, it takes time to degenerate to a subatomic level and then merges in the dark matter.
there's nothing that can make the earth spin faster than it does. instead, it is slowing down, albeit very slowly. some day it is going to stop spinning and then will get sucked by the sun's gravity-provided the sun is not dead already!

Because the earth fears of slipping away from its axis of rotation...don't push it too hard to spin faster and faster...

I read something about the "Shuman Resonance" im not sure if you have heard of that but its very interesting maybe you should check it out, go into google.com and do a search. Its interesting as it relates to possible earth changes including rotation etc.

On the contrary why doesn't it stop? Where does the energy come from to make it spin?

Its slowing down the moon is moving away
the sun holds us with its gravitation,
the earth also wobbles which give's us seasons.
