I tried to figure out stuff once, but really didn't have enough time. Big corporations & Individuals are pumping money everyday into it. Not 100% sure, but I've heard that some have made million $s real-life money from second-life.
If you think it's for you, go ahead. It's a waste of "real-time", imho, well unless you can get the real-life $$$$$$$s in return. Keep us posted how it goes for you!
