I think is like someone else above said.. that you put more strong feeling towrds that word.. it's like when you are yelling at someone on chat you HEY YOU!!! COME HERE! so thst's stronger than hey you! come here!
It looks totally diferent!

and it's End of the World

I guess it looks cooler too. Like instead or writing VOGUE or Vouge she wrote vogue beacuase who the word is presented.. like.. making capital any letter would not create smooth name.. i don't know if i make mayself clear.. it has to do with the design how the word looks the best.
