Please don't peddle your view of some obscure, dated Sci-Fi as "The greatest work" ( The End of Eternity WAS NOT, by far, Asimov's greatest, in my opinion), or "timeless Classic" (The Humanoids isn't; again, my opinion).
It's fine to have an opinion, but it's not necessary or proper to state such as fact and be "startled" by someone else's lack of agreement in it (or ignorance). Nor is it right to besmirch the integrity of "people" who do not agree.
I love a large portion of the books on this list. Others I can't believe are on here. But it is _A_ list produced by _A_ group of people who were probably asked _A_ specific question. They did a pretty decent job too (my opinion), as can be witnessed by the fact that most of us have read most of these (I presume based on the remarks).
Anyway, sorry to rant, but it irks me when someone trots out a couple of fairly obscure references as evidence of other's simplistic ignorance.
