About a year ago in my first visit to Second Life, the popular online virtual world, I spent half an hour trying to make my avatar, or online character, look like a hotter version of myself — which isn't easy when you don't know how to use the tools. When I finally made it onto Money Island to mingle, a stranger approached me and said, "Hello there, Devon." I froze. Then I tried to run. I was desperately searching for the teleport tool when my sister walked into the room, peered over my shoulder at the computer screen and said, "Why'd you make your avatar ugly?" I logged off.
