I do have a legal name - my birth name. It's but one of many. Why is my legal name important? It isn't. I don't even consider it my primary name. The concept of one single "real" name is severely retarded and flies in the face of reality. We need to get rid of this concept, along with the illusion of a single identity. I simply am not the same person when I am with my parents, when I'm with my meatspace friends, or if I'm hanging out on IRC with people I know pretty well, but have never seen or met. I'm someone different here on HN than I am on 4chan, or any other message board. That's perfectly human, and no company or law will ever change that.
