It's a great web site when you look for information, that is true. YOu can learn a lot here, I sure did. It helped me a lot to discover myself. However, if it is good for kids that is questionable. There is a lot of sex talk, and some opinions can be radical. Also there is some bad language there.
For adults it can be good, but I don't know if I'd let kids there so much. Though, even for an adult it can be too much. For me it has been. It's way too sex-positive.
