Depressed People Surf the Web Differently
It turns out depressed persons spend a lot more time flipping around the Internet randomly, have less consistent usage times and use more file-sharing programs and (this one surprised me) sent out more e-mails.
Researchers said the random Internet patterns (such as watching a video followed by an email to watching part of another video to reading part this article, etc.) could point toward trouble concentrating, a symptom of depression.
Usage itself was erratic, too: some students would spend hours a day online then not touch the computer for two days.
