The geek in me wanted to check it out. I was into 2nd Life for a while (quite a while back) but since I don't know how to write script, I was limited in what I could do. I did make a little money participating in polls where you enter a room that looks like a class or a lab, and they had you perform certain tests. At the end they would pay you.
It was kinda cool. There was also some talk about college classes being put on 2nd Life, but it didn't come to fruition for the colleges around my rural area. There was a 2nd Life 'set' for the college I was attending, and a few departments did do a few other things -- mainly the anthropology and science departments. There just wasn't enough interest, because many people around here are still new to computers, and had a hard time navigating.
Thanks for giving me something to procrastinate over investigating! :geek:;)
