"Also, mild inconsistencies... the Trace? What happened with Dobby and Harry in book 2 then? I also distinctly recall them having some sort of discussion about that and Ron saying that in wizarding families they can't really tell who's doing the magic, so it's on an honor system? And Harry thinking it was unfair? So what's this about a specific Trace on you ‘til you're seventeen? hmmm."
The Trace detects any magic nearby, whether it's done by the person with the Trace or anybody else. So, they cannot tell if Harry is the performer of magic or not--they just assume that if magic happens near him, it was his doing, because there are not supposed to be any other wizards in his vicinity back at Privet Drive. Thus, the Trace wouldn't be too effective with someone like Ron, as he's pretty much constantly nearby his wizarding family members. Thus, I don't find the Trace to be a very inconsistent point.

"Dumbledore already dying from potion slightly anticlimactic"
Dumbledore was actually dying from the curse placed on the ring.

Again, Nineteen Years Later was =/ . No one named after Fred? HOW COULD THEY. T____T Fred, oh Fred...
The original epilogue contained much, much more, including the names of every child born to the Weasley clan in the last 19 years. JKR revealed in a Bloomsbury webchat yesterday that George's first child was named Fred. You can find the webchat (it's really interesting and answers a lot of questions) on leakynews.com or mugglenet.com

Hedwig's and Dobby's deaths made me sob so much. Jo tells us why she decided to kill Hedwig in that webchat I mentioned.
