How Do Netlfix Users Choose Movies?

(5/21/2014) The result is not surprising. But I am surprised that "75 to 80 percent of what people watch on Netflix comes from the site's recommendations rather than from search" . That percentage is very high. 

Now,according to a Huffington Post's report, Netflix will revise its recommendation to its users. It says in the future they may only give users 3 to 4 more precise recommendation in stead of long grids of movie titles for users to browse. Is it related to Net Neutrality and the fee Netflix pays to the Internet service providers?
