Oooh, there's one point nobody's mentioned: How the word "muggle" entered the pagan vocabulary after the publication of HP. You feel a bit dirty after saying it, but it still serves as a term for non-magic-users which was kinda lacking before.
I do not use that in every day life, and I barely use it when talking about Harry Potter. The people who use that seriously need to get a life. I am guessing that the ones who use it are probably fluffy bunnies or they just think they are better than people who do not use magic. I am sure they would call me a muggle as well because I do not cast spells.
