Imagine meeting people online via an immersive virtual environment for work, play, or romance. This happens every day. Second Life is the most influential of virtual worlds in our current technology landscape.
Second Life is a disruptive technology. It provides an avenue for people to communicate, live a digital life with less restrictions or inhibitions, work from home, build personal and romantic relationships. It can be a considered an immersive social network that can be used for business but is in many ways more of a personal expression. I think that Second Life is already in decline and will be replaced by other new communication and/or social networking tools that will incorporate but not only be limited to virtual worlds. I think that Second Life has limitations in K-12 settings due to privacy issues, restrictions and the inability to manage Second Life from a teacher's point of view. It may have limited use as a teacher-centered technology tool. One recent study about Second Life in K-12 and Higher Education can be accessed here. I think Second Life will be gone in 3-5 years facing a similar fate as MySpace, which is currently in steep decline.
