Why are we using Secondlife?

Some people are using Secondlife for different purposes and they can be classified into three catogories according to why they are using it: for fun, for education and finally to improve their English. First category is for fun and I think people in this category don't have any purposes. Because they only spend time at Secondlife. They can listen to music and they want to meet new people from everywhere and chat with them etc. They are the most common type I think. And also second category is for education. For example at METU, we have to use it for Advanced and Reading lessons. And the last category is to improve English. Of course thanks to Secondlife, we can improve our English. But for it, we must talk to people who can speak English...
