Are you talking about the Ex version of it only? Because the Su version from the shadowdancer has the whole "As long as she is within 10 feet of some sort of shadow, a shadowdancer can hide herself from view in the open without anything to actually hide behind."

Or even then do you need the shadow to grant concealment? Because if so, it kinda loses the point doesn't it?
