Swing Dance Styles

I'm now learning West Coast Swing, which only seems especially difficult to me because all the swing dancing I've done before derived from Lindy Hop, the original swing dance from the 20's.  When I learned swing dancing in California in the 1980's, what I was learning was Jitterbug, a simplified version of Lindy Hop from the 30's.  Another simplified version of Lindy Hop from the 30's, and later standardized, became East Coast Swing.  But the original Lindy was generally considered the most athletic, most challenging, and had the most variations and potential improvisations of all.  Finally, West Coast Swing, an entirely different dance, was invented for dancing at concerts in the 40's and 50's.  Lindy Hop is a stationary dance you can do in one small spot if you need to, like on stage, and West Coast Swing is a panel dance you can do in one small floor area, going back and forth but never exactly stationary.
