People get annoyed when the boards are cluttered wiht topics that have been asked repeatedly. Imagine the American Coasters board being filled with topics like:
-What's your favorite coaster?
-Is Superman: The Escape a coaster?
-Cedar Point vs. Magic Mountain
We have to close all of those posts in an effort to keep our discussion fresh, so on the same token, we have to close your topic even though it is less-frequently asked. It's not personal. We're just enforcing the rules that were laid out for these boards.
