Facebook Usernames are now live. You can now register your “facebook.com/username” to easily share your Facebook profile with friends. This was one feature Facebook was missing that other services offered that made it easy to share your profile, such as Twitter.

Your Facebook profile has went from a complicated URL structure of http://facebook.com/profile.php?id=111111111 to http://facebook.com/yourname

The feature has just gone live, and in about 15 minutes after the launch, there have been over 500,000 registered usernames, so grab yours before it’s gone.
