This guy needs no introduction. He is the reason this honours “contest” even EXISTS! Due to him, millionaires have been created. Due to him, kids who would normally be out playing football are now able to become international superstars by using nothing but their fingers.

And if that is not enough, you probably all know that he (with the rest of Automattic) gave the trademark of WordPress to the WordPress Foundation so that it will be protected and stay open source forever. If you don’t vote for him, you are either evil or part of Joomla!
