I am new to this website, so forgive me if this point was mentioned 
in earlier posts.

I was troubled that Harry and Company took the Knight Bus to the 
hospital when visiting Mr. Weasley.  If the OOP members were trying 
to avoid giving away the location of their headquarters, why would 
they hail a bus right in front of Grimmauld Place?  Given that Harry 
is a celebrity in the Wizard world, his boarding the Knight Bus would 
probably be passed around and could get back to a DE.  If someone in 
Voldemort's camp heard about this incident and remembered that the 
Black House was located on Grimmauld Place, they could easily make 
the connection.  Granted they wouldn't be able to actually see the 
Black House because of the Fidelis Charm, but if any DE's staked out 
that area, they would surely see the Weasley's and others coming and 
going.  This just seemed like a weak plot point to me. 

Otherwise, I really enjoyed the book and liked it better than the 
GOF.  The POA is still my favorite of the five.
