Okay, I don’t alltogether agree with the list, but that isn’t what I’m looking for, so put objections aside for the moment.
So, how many have you seen?
Zero.
And, I won’t have any heartburn if I don’t ever see any of them. I’d have enjoyed traveling as a youngster but now I’m old and set in my ways. Grumpy, even. 
ETA: I did go to NYC a couple of times but I don’t remember paying attention to the skyline much.
26
Three: NY skyline (both before and after 9/11), Niagara Falls, and San Francisco. I might add the Notre Dame de Paris, which I have seen both the inside and in a “Son et Lumiere” show. I would also add the Chion-In Buddhist temple in Kyoto, just about the most impressive room I have ever seen.
Could you expand on your answer a bit? I want to be able to properly drool at the thought of all the cool things you’ve seen that I likely won’t ever see.
A paltry four. All in this country. I’ve spent an hour in Canada and grand total of a day in Baja California in my entire life, so the wonders outside of the U.S. are still waiting for me to put my passport to some good use. Some day! <shakes fist>
Oh, the ones I’ve seen are the NY skyline (just this past summer for the first time), the Grand Canyon (twice, for about 20 minutes), Yosemite and San Francisco.
Ten. The NYC skyline and the Met are right here for me. Others:
Amazonian rainforest (in Peru)
Sahara (in Morocco)
Marrakesh
British Museum
Machu Picchu
Jerusalem Old City
San Francisco (the whole city?)
Niagara Falls
Obviously this is rather arbitrary. Are the fjords of Norway that much better than the fjords of New Zealand, which I’ve seen?
The Grand Canyon
New York Skyline
San Francisco
British Museum
Yosemite NP
Yellowstone NP
Eight.
Louvre Museum
Versailles
Mont St Michel
Stonehenge
New York skyline
Eiffel Tower
British Museum
San Francisco
I actually saw all eight of them within two months. I still think Chicago has a better skyline than New York.
I’ve only seen five, although about a quarter of the items on that list don’t even interest me. My top 100 places to see would be wildly different.
No Hawaii?!?
16: Forbidden City
32: Fjords of Norway
37: Hong Kong
41: Louvre Museum
43: Versailles
47: The Met
57: Chartres
79: Stonehenge
81: Yellowstone
84: Manhattan skyline
86: Eiffel Tower
89: British Museum
92: Yosemite
99: San Francisco
Grand Canyon - missed it.
Basically some business travel, vacations in France and the UK, and a couple trips to China. One trip to Italy would nail another stack it appears.
Dude, nobody pines for the fjords of New Zealand
5 BTW: NY, SF, Niagara falls, Yosemite, Grand Canyon ETA oh yeah, and the Met, so 6.
Well, I’ve been to 48, I think. I spent a year and a half traveling around the world, 3 months backpacking in Europe after college, plus I’ve been around the USA quite a bit. A lot of these places are twofers (Florence, NYC, Venice, Istanbul, Vatican City).

As you can see from this list, I have travelled extensively in North America and Europe, but not much elsewhere in the world.
One
It would have been two if the grand Canyon hadn’t had a flash flood during my vacation.
How did the Corn Palace not make the list?
Yeah, that list calls for some proper droolage, excuse me while I go get a hanky.
14: Louvre, Venice, Versailles, Met, Chartres, Uffizi, St Mark’s, Florence, Mt-St-Michel, NY, Eiffel Tower, Niagara Falls, British Museum, and San Francisco. Hoping (OK, pining) to add the Fjords next year.
I’ve seen exactly one- Yellowstone, which I drove through one day while traveling across the country. I’m now very depressed.
I’m also a bit surprised that Crater Lake isn’t in that list. It should be.
