Second life anyone?

So in one of my classes last week, my teacher talked about all the new and facsinating technologies out there today. His presentation included i-report, second life and i-report second life. Prior to this class, I had no idea these existed and I was astounded. It is becoming so much easier to personalize every bit of our lives. Anyone can shoot video footage of what they think is newsworthy and put it online for the rest of the world to see. In second life, everyday people can make up a virtual avatar of whoever they want. They can then do whatever they wish. People are actually making a steady income through second life. It scares me that I had no idea there was something like this out there when it is such a big deal, with so many advantages and disadvantages. I do think controversy with arise from programs such as this. I think this is just the beginning and am curious to see where this virtual world thing goes.
