I think this is a fine place for these issues now, as they're important to the community and the reaction has been positive. It will help drive awareness and encourage others to seek help. Unless of course he successfully creates a help net work, then it might be time to fork off to there :)
Although it sounds like you are joking, I just want to note that this can be quite a dangerous approach. Depression isn't just "very sad, needs help to cheer up". Depression is a neurochemical problem possibly caused by or exacerbated by environmental effects. Amateur psychology and "the power of positive thinking" are the equivalent of homeopathy. They work for some, but not reliably better than the placebo effect.
Depressed people need head doctors in much the same way that physically injured people need body doctors. For mild cases "walk it off" might work (in both head- and body- problems), but depression is more like a broken bone than it is like a mildly sprained ankle.
