For nearly all of my publicly-facing online identities, my name is the handle. Consider, for example, Flickr and X, which I joined in October 2005 and December 2006 (when Twitter), respectively. I set up Facebook in October 2006, long before the service allowed anyone to choose a handle.
On June 13, 2009, at 12:01 a.m. EST, Facebook opened up the landgrab to claim a personalized username. That worked out to 9:01 p.m. on the 12th for we Westcoasters. Unfortunately, I was nowhere near a computer, waiting with our daughter for her flight from Long Beach, Calif. to one of three major Washington, D.C.-area airports (I don’t recall which).
