One More Take on Identity

After having just written two columns about identity, I'd like to change course by writing about ... identity. But there's a difference: my previous columns dealt mostly with how information available about us on the Internet has evolved in recent years. Here, I want to think a little more deeply about the methods we use to identify ourselves on the Internet - how we do it now, what's wrong with the current approach, and where this notion of identification might go in the future.
