Recently, I took a tour of Second Life and learned about all the cool stuff you could do and man: was it neat. There are literally endless things that you can do on here, it really is a second life. One of my favorite things is being able to buy gifts and packages. I like this because it really symbolizes a community where you exchange things back and forth. Another cool feature is the camera. It acts like a real camera where you an zoom in and out and capture anything you want to.
With the wandering, it may seem pointless, but from an educational standpoint it is very beneficial. This teaches students to more or less 'get out there' and explore. Exploration is one of the key principles in learning (in my opinion), and if this teaches students to get out there and explore a new world, then they may be less hesitant about exploring the world in which they live their first life.
