Depressed people surf differently.
 

From Medical Daily:

"Researchers led by Sriram Chellappan from the Missouri University of Science and Technology, collected internet usage data from 216 college students enrolled at the university. The usage data was collected anonymously without interfering with the student’s normal internet usage for a month. The students were tested to see if they had symptoms of depression and analyzed internet usage based on the results. Depressed students tended to use the internet in much different ways than their non-depressed classmates. Depressed students used file-sharing programs, like torrents or online sharing sites, more than non-depressed students. Depressed students also chatted more and sent more emails out. Online video viewing and game playing were also more popular for depressed students."

File-sharing, check.
Game playing, check.
Chatting, never; e-mails, fewer than most.
Depressed, check (my actual diagnosis is PTSD).
"The usage data was collected anonymously...", scary!

File-sharing, check
Game playing, very little.. well only if poker and betting are included, then some.
Chatting, check if forums, PMs are included
E-mail, a lot at work, very little privately
Depressed, no.. or very light due to stress caused from lack of sleep/non existant sleep cycle.
Severe insomnia, check

File sharing - always.

Game playing - yes, if playing in the Arcade here counts. No RPG.

Chatting - same as Sleepless...only forum PMs.

Email - comes & goes, but not a lot generally.

Depressed - no. But again, like Sleepless I have a problem with insomnia :timetosleep:

File-sharing - heavy (lol) but periodic
Game playing - a lot recently
Chatting - same as birdy and Sleepless
Email - not a lot
Depressed - yes, insomnia - yes, sleep cycle - all around the world. :D
