It did create a lot of talk out of the classroom, but that's not always good. I am often exposed to anti-science people who use this decision as further evidence that scientists don't know what they are doing or that they lie. As someone who was working on a M.S. in physics, they've always regarded me as some sort of anti-Christ, especially since I am an atheist. Trying to explain to them that this was actually about language rather than science doesn't help. They won't accept the idea that science is a process, not some sort of global conspiracy perpetrated by Satan and "demoting" Pluto really fuels some of their arguments.
The fact that it is a controversial matter in the scientific community actually seems to help polarize anti-science Americans even more. They see it as some sort of "shady backroom deal" in the same way they characterize, not coincidentally it would seem, discussions had by Democrats that influence political decision. Science is a left-wing tool to these people. We have a Congress that felt it necessary to reaffirm a cold-war era motto for our country to protect it from a liberal threat that didn't exist.
We have a very large group of people in America who are so sure of their world view, and so scared of it being challenged, that they must play Zeno's Paradox with the missing link. make personal relationships about religious morality, and can't accept a solar system with only eight planets. Maybe Europe doesn't have these problems but in America, it's worth considering when creating an arbitrary definition. Of course, that can be problematic as well since we now have pizza, made of grain, dairy product, and fruit minimum, now defined as a vegetable so parents and schools don't have to feel guilty about being cheap and lazy.
