Voldemort made a point to visit Grindlewald at Nurmenguard (sp?), and 
I really am wondering why...

Was he like the ONLY person in the Wizarding World who did not hear 
of Dumbledore's defeat of the Dark Wizard Grindlewald?  What, did 
Voldie never read a Chocolate Frog card?  Poor deprived child... 

Shouldn't Voldie have known that he wouldn't get the wand from 
Grindlewald since Dumbledore defeated him all those years ago?  

OR...

Did he just want information?  Proof that Dumbledore did have the 
Elder Wand after winning it from Grindlewald?  I thought he KNEW that 
Grindlewald had it through his legilimency performed on Gregorovich?

Was it just writer's license so that the reader could see Grindlewald 
and Nurmengard?  Prove that Grindlewald perhaps loved Dumbledore 
still by trying to protect his tomb from Voldemort's greedy fingers?

Inquiring minds want to know... :)
