I have been on SL for nine years. The negative is it can be a little daunting when you first arrive and dont know how to do things. I was lucky in that someone gave me a few pointers. It is a comunity and is a second life and has great things to do such as sailing and flying , live performeres and lots of varied comunities. Yes some are adult but you dont have to go their just like the real world. I have not tried to make money on SL and I spend money because I wnat a super avatar and like my fashion with hundreds of clothing stores. I alos pay for a beach side home. Just keep to a budget. I have never been scammed and you just have to be careful like in the real world. The quality of the graphics is constantly improving and is good enough for me . I have made friend with people all over the world. Its a great social place and tought me about other cultures. Because its global you find things get busy at certain times depending what time zones your in. I love it . Its not for everyone but ticks my boxes.
