Nope! The moon _does_ rotate on its axis -- one rotation for
every revolution about earth.

It's confusing, but let's hopefully clarify it with the
following example. Imagine walking around a chair with somebody
sitting there and watching you. Let the back of your head be
the far side of the moon and your face the near side.

Start off south of the chair and facing north. The person in the
chair sees your face. If your head did not rotate as you walked
around the chair, then you would always be facing north. When
you got half way around, you would no longer be facing the chair
but staring in the opposite direction. The person in the chair
would now see the back of your head.

On the other hand, if your face is always pointed inward toward
the chair, your head will make one complete rotation for every
circle around the chair. E.g., when you got half way around, you
would be facing south instead of north, or one half rotation of
your head.

>The dark side is always dark and the light side is always light.

If that were true, then there would be no phases of the moon.
The far side is often erroneously called the "dark side" of the
moon, but like the near side, it rarely is completely dark.
E.g., when there is a "new moon" the near side is completely in
shadow and the far side is facing the sun and completely lit up.

>This is one of many anomalies about the moon.

No, it is not an anomaly. It is a well understood phenomenon
called tidal locking, true, e.g., of the planet Mercury as well.
It also has one side perpetually facing the main body it is
orbiting, namely the sun. The larger body eventually slows the
rotation of the smaller until its rotational period eventually
equals its period of revolution.
