This is a prime example of the false sense of achievement that Second Life can provide for its users. Given a serious case of stage fright, the girl could never bring herself to perform anywhere other than in this virtual world. The problem with this is that as long as she continues to use the site as a means to express herself, she will never learn to socialize and interact with people in real life. Not only this, but she is also given the opportunity to be whoever she wants to be within Second Life. This may sound like a positive outlet for people to express themselves as they could not or would not in real life, but I think it's a slippery slope to losing yourself. If you change so many attributes about yourself in order to "improve", chances are you're going to become dissatisfied with the person you are in real life. This does not exactly encourage a healthy sense of self.
My overall impression of Second Life was skeptical to say the least. It appears to me to be nothing more than an alternate virtual community that gives people an excuse to escape/avoid the reality of their own lives, pretend to be something they are not, and indulge strange fantasies that should be dealt with by a psychiatrist. I mean really?-- sex? That's just weird.
