Don't mean to be big headed, but I'm actually a pretty good dancer already and I can testify that its a major advantage to be able to dance - I have good rhythm, a few decent moves etc, and I certainly get more attention for it.
I have noticed before that girls will start to 'hover' around me after I've been cuttin some shapes on the dance floor for a while.
Just in the past, its been the rest of my game that has let me down from capitalising on it.

I think apart from anything else, it's a good socialble skill to learn. If all this stuff is about self-improvement, then learning to dance is up there with learning an instrument, or a new language etc.

In fact, I have just thought of a phrase that sumes up PU, and is as simple and all-encompassing as Kowalski's sig:

Be impressive

Much love,
