When I see a list. I know what is on the list is going to depend on who is making the list. There are some predictable ratings, but there are generally surprises. When looking at Sci-Fi fiction lists, it continues to be amazing that there are so many authors writing who were hardly recognized, but produced high quality work. Short stories are great because they can be read without like seeming like a project. They are also good for training our minds to read epics.(I've just clipped the two ends of the list.)

There are some good ones. Ender's Game is number three! Great. But where is Snow Crash?

From the site-About the site:
"People wanting to delve deeper into how the lists are constructed would do well to start with the links page. The 'Other Lists' section gives some clue as to the main sources of info used to construct the original lists. A word of caution though… most are based on the opinion of others and, from a statistical viewpoint, are not good representations of the true state of affairs. No list is perfect, but in general the ones heavy on source data are usually the best."
You can vote, but I'm not sure how to vote on a story not in their list. I'm sure they accept suggestions, but the Recommended links" are to other lists, and Great Sci-Fi websites.

Edgar Rice Burroughs should be on that list. Asimov is good but not THAT good. I am happy to see Orson Scott Card but where is Fred Saberhagen?
