Interesting throwaway on Hermione at JKR's updated site (dragon's blood)

Not sure if anyone other than me will find this interesting, but one 
of the scrapbook items you get when you solve a clue (or follow 
someone else's instructions, as I did ;-)) is the original synopsis 
of PS/SS.  I noticed a little tidbit near the end:

"...and Hermione Granger (cleverest girl in the year and the only 
person in the class to know all the uses of dragon's blood)."

Huh.  Does this surprise anyone else that Hermie KNOWS the 12 uses?  
I thought only DD knew them all -- or at least that none of our main 
kid characters did.  So far we readers only know a couple of them, 
right?  Oven cleaner, for instance.  I wonder why Hermione hasn't 
mentioned more of those uses along the way?

Not sure what this does to my DRIBBLE SHADOWS theory -- that Snape 
concocted a protective potion for baby Harry which included dragon's 
blood.  Would Hermione have guessed at such a thing if she knew 
dragon's blood could be used in such a way?

Maybe.  Maybe not.

Jo may only have meant that bit to be an example of Hermione's 
advanced knowledge re: her classmates, but I do wonder if it isn't 
also a specific example which is also going to come into play somehow 
before we're through....
