Why is Vincent Yelling?

I came across Vincent Orange's website today, and I have a question. Why is his letter on the about page welcoming people to his website all in capitals? Take the opening for example:

"HELLO I'M VINCENT ORANGE AND WELCOME TO THE ORANGE FOR MAYOR WEBSITE."

Sure he seems excited about running for mayor, but it strikes me as similar to how excited this guy is put me in a new car TODAY.
