[Air-l] Disadvantage of the Internet

Dear Air'ers, I am looking for the literatures dealt with "disadvantage" of using the Internet, computer technology, webpages, or blogs. I know it might be a sort of embarrasing topic. I prefer the micro-level or psychological aspects (annoyance, time sink, harm, and the like) to the macro-level or social aspects such as privacy, anonymity, and participation. I'd appreciate any help here. Kyun-Soo Kim
