How so? I'm willing to admit that maybe you know something I don't, so  
please clarify: if I have 'box-shadow: 0 0 8px black' then what is 8px  
the radius of? Where is the other half of the circle for which 8px is  
a radius?

Right. It wouldn't change authoring or implementation (maybe a few  
blogs would need updating). I think I'd be more comfortable with  
something like this:

"The blur is perpendicular to and centered on the shadow's edge and  
defines a gradient color transition ranging from the full shadow color  
at the endpoint of the blur inside the shadow to fully transparent at  
the endpoint outside it."
