I think the "like" button made everything cheaper. We don't have a button like that in a real book or a movie, can you imagine how jaded your experience would be if you felt like you were being judged for liking a book or different parts of a movie.

 

The like button went from, hm, I'm not sure what to say, but I like it or you, to... "This is popular."
