What is your purpose in reading SF?
Do you want to be better able to understand the sort of references someone on Less Wrong might make?
Then I’d suggest The Moon is a Harsh Mistress, A Fire Upon the Deep and Accelerondo.
Do you want to be exposed to a lot of futurism ideas?
Then I’d suggest Permutation City, Blindsight and Rainbows End.
Do you want to read something that’s just fun?
Then I’d suggest A Civil Campaign, On Basilisk Station and Ender’s Game.
All of these books are written by people who have written multiple books, if you find you like them, you can easily read their other titles.
