^ Hmm, that's really interesting..But I don't think a lot of them are plot holes (unfortunately, as I like a good debate too). I think they're typos or JKR forgetting little details. There's a big difference between a *plot hole* and a mistake. But there are some valid ones, and I think the good ones are:
*In Kreacher's Tale, if the potion was never put back in the bowl, then I suppose that it shouldn't have been there when Dumbledore and Harry went, although I'm still leaning towards the theory that there might be a refilling charm or something after a certain amount of time...
*Plumbing in the Chamber of Secrets 1000 years ago? I guess it's a valid point, although I'd like to say that we're Muggles, sadly, and therefore have no idea when plumbing was created in the Wizarding World (possibly 1000 years ago...)
*"When Voldemort was resurrected with harry's blood and gained the ability to touch him, wouldn't that mean the the protection in dursleys home be bypassed to?" Extremely good point, and I have no good answer for that one :)
