Digg and reddit aggregate links across a wide variety of topics and have a very diverse user base. Stack Overflow's focus is more narrow (much like that of Hacker News). The crowd is a lot more focused as a result. People are a lot less easily influenced by writing style than by correctness. (Try posting code that won't compile and see what happens.) Yes, people are influenced by reputation and good writing on subjective questions, but those are discouraged on SO, and they don't really have one right answer anyway.
