WordPress, the free open source project, turns 15 years old today. Here is the comment that started it all. In addition to celebrating 15 years as a successful software project, it's also a good opportunity to reflect on the number of people across the world who are making a great living and turning dreams into reality thanks to the project. Thank you Matt Mullenweg and Mike Little for creating WordPress, its contributors for keeping the ball rolling all these years, and providing opportunities for so many people. Happy birthday WordPress!
