Or how about this: isn't that an inherent flaw of the entire Internet? Anybody can buy a domain and say any horrible thing about anybody. I think she (and the media by and large) is missing the big picture.
I don't think they are missing anything, they just have different values. Wikipedia works on the principle that a small amount of incorrect information is an acceptable price to pay for a large amount of correct information. When the incorrect information is negative stuff about a particular person, that person tends to disagree - it's understandable, really.
