Much of this seems rather intuitive, i.e., no one pays any attention to me, so I feel sad. What interests me, is how new media may affect certain types of mental illness in general, i.e., addictive behaviors, depression, mania. This study is a start, but if Turkle is right, i.e., we are more connected, yet also more alone than ever before, then more longitudinal studies are indeed in order. Like much of mental illness in general (unless we are marginalizing this condition as a lack of self-esteem) this seems more situational than typical. What do you think?
