It's neat to see how rides match up to others, but that poll doesn't hold a lot of water for me. It has it's flaws.
1) There are too many foreign coasters at the top of the poll. That's not to say that there aren't great wooden coasters outside of the U.S., but the poll is very much skewed to the rides that don't see a lot of voting riders every year.
2) The poll requires voters to rank every roller coaster they've ridden from 1-whatever, or rank them in groups - both of which are really impossible to do. I've ridden a lot of roller coasters, and it's hard for me to create even a top ten. Additionally, not everyone votes the same way.
3) People have different preferences and tastes. What makes a top 10 ride for me is not the same for everyone else.
4) The poll is very heavily influenced by TPR, let's face it. They advertise the heck out of it, and all of their minnions vote - many voting the same way. There are also a lot of Alvey brown-nosers that would follow him off of a cliff, let alone like the same rides, simply because he's ridden so many.
For example, if you're one of the 45 that voted for Twister at Grona Lund, you probably went on the TPR trip there and were influenced by general group's opinion. I find it very hard to believe that it is "really" the 14th best wooden coaster in the world.
I understand that this poll tries to account for all of these variables. While I respect the effort, you ultimately can't escape partiality. And when it comes to roller coasters, there are a lot of biases.
I guess my problem isn't so much with having the poll, it's that a lot of people accept it as gospel.
Instead of one large poll, I would much rather see what individuals would rate as their top 10 rides.
