Default KV Rating??

Can someone please define "KV" for me, please? I'm not comfortable with Wayne Miller's definition of "1000RPM per volt". I can believe it describes a motor's RPM as a function of applied voltage but I can't figure out the relationship. I guess applied voltage depends on ESC and throttle stick position.

I suppose my question is really "what does KV tell me about motor performance and how do I use the KV specification"?

Any ideas for me?
