Only four years?! Wow, things change fast...
Happy birthday YouTube!

At Feb 15th 2005 youtube.com was registered.
When you say it for Google like Websonic does for YouTube, Google's Birthday would be in September 1997

"The domain name "YouTube.com" was activated on February 15, 2005,[3] and the website was developed over the subsequent months. The creators offered the public a preview of the site in May 2005, six months before YouTube made its official debut."

Omg. My Friendster account is much older than Youtube. It'll be turning 5 this December.
