One of the things I find most interesting about the Internet and living an online life is the way I can control and shape identity, largely free from the constraints of real life. That doesn't mean, for example, that I pretend to be rich and glamourous under my pseudonymous self (or a 55yo overweight truck driver from the Bible Belt, for that matter). What it does mean is that I control my identity online.
Sometimes, like here, I use my real name and images that approximate my real self. I talk about my job or my writing or the state of my desk (exciting, exciting and cluttered, respectively). But sometimes, I use other online identities that don't intersect with people that know me as a teacher, writer, or person incapable of cleaning. I like that. The people I meet that way don't need to know about my struggles with an appropriate resolution for my next novel idea, or about my frustrations with exam supervision – though some of have become friends with whom I share my real life.
I think that privacy and identity are two intertwined concepts when it comes to living part of your life in online spaces. I need to be in control of both my privacy and my identity – and isn't that a new way of looking at things? I like my 21st century responsibilities. And my 21st century opportunities.
To answer the original question… I like my name. It's interesting and unusual, and it has a certain old-fashioned charm that is mildly incongruous with my actual self. If I was to change my name, I would almost certainly choose something in Maori, something that roots me in my identity in this time, and in this place, in the real world.
