Any "best sci-fi" list is like a selection of favorite candies. There's fleeting pleasure and some novelty to the experience, but it is what it is and in quantity it's bad for you.
If you want to read literature, choose something that will at least make you think better, not just dazzle you with future tech.
I've read Solaris few years ago, and Ender's Game few months ago. I like both books and I do not see a reason for bashing EG.
Could you elaborate?
The demise of any social website also seems to coincide with the first mention of Ender's Game. Could this be the end of HN as we know it?
I don't think that's a good rule at all. Ender's game a is popular children's novel and is likely remembered fondly in any techie/nerd/geek setting. It just shouldn't belong at the top of a "best of scifi" list.
