Are you saying that the person doing this has no conscious access to his or her own latent reasons? Or that this is just a random pattern like a Rorschach? I don't think it is a random pattern. There are far too many xx usernames here, relative to the other online communities I am a part of.

I'm saying that trying to surmise what someone is thinking from their choice of a two-character handle is like interpreting a Rorschach, which is not the same thing as saying that the characters themselves are randomly generated.
