For some reason, this post in the WoW Europe general forums asking what shapeshift form has the best dance moves makes me suspicious. The poll itself is innocuous enough, although I don't understand why Tree of Life and Moonkin carry such a commanding lead (Cat is my personal favorite).
No, the suspicious part is: why are they asking this now? New dances were a much-hyped feature in Wrath of the Lich King, although they have so far entirely failed to materialize. If they're still working on them, for 3.3 or 4.0, this might be some market research to see what sort of dances we like.
On the other hand, it may just be an innocent piece of fun from Ancilorn. Who knows?
