Second Life

Much more than a 3D chat, Second Life is the most significant virtual community on the web and also the most widely accepted by Internet users and society in general.

Now it's possible to start a new life without even leaving your house: looking for a job, starting your own business, going to concerts, and finding your soulmate are some of the things you can do in Second Life.

This fictional world even has its own money (Linden dollars) that, like other types of currency, has its own exchange rate tied to the value of the real dollar.
