The debate on this could go on forever. There are just so many elements on coasters out there that would create so many different categories, thus creating mass confusion. The poll, as it exists now, is fine. It's simple, direct and mostly all-inclusive to the trends of the general public. Looping, non-looping, hyper, giga, inverted, stand-up, suspended, mine train, wild mouse, launched, 4D, vertical drop, etc... these all could warrant their own catagories, and most do in smaller independent polls. The industry, media and the general public, however, tends to lean towards this more straight-forward simplistic rating as set forth by Amusement Today.
I do tend to agree that there are many gems out there that get overlooked on these polls, but being one that is anti-polls or anti-top 5, 10, 25, etc... it really doesn't matter to me at all. I know what my favorites are, and I could care less what someone else thinks about it.
