According to Facebook founder Mark Zuckerberg the online community is hitting another milestone with membership climbing to 400 million this week.

“Today we're celebrating our sixth birthday, and this week there will be 400 million people on Facebook. Just one year ago we served less than half as many people, and thanks to you we've made great progress over the last year towards making the world more open and connected,” Zuckerberg said in a blog post. “So to celebrate six years of Facebook and the 400 million people on the service, we're doing what we like doing most - building and launching products for people.”

Zuckerberg said Facebook began six years ago as a product to help people around us connect easily, share information and understand one another better.

“We hoped Facebook would improve people's lives in important ways. So it's rewarding to see that as Facebook has grown, people around the world are using the service to share information about events big and small and to stay connected to everyone they care about,” he said. “After the launch we're going to celebrate with a Hackathon - an event where all of us stay up all night coding and building out our new ideas for our next wave of products for you.”
