Interestingly, I started hating PHP when first doing a personnal project in college. It was a complete unmaintainable mess. Later, when I used it professionally, I learned to do things right (using frameworks and the like) and started liking the language. I think hating a language is more about what you had to do with it, and how you did it.

On another note, I'm surprised not to see Javascript at all in the list. It used to be seen as one of the worst languages to work with. It's weird how fast these things can change.
