The 6.30.13 Issue - NYTimes.com Instead of lamenting the fact that Wales is not superrich, a point could have been made that most great things in this world are not a product of monetary incentives. The fact that Wikipedia is what it is makes it stand far above all the Silicon Valley gloss. JOHN, California, posted on nytimes.com Wikipedia always catches flak because a teenager can edit an article just as easily as a college professor. This is true, but if the subject is smartphone apps, the teenager probably knows more than the professor. And unless the article is about something obscure, like Yemeni history from 1350-1450, thousands of people will view it, and someone will correct any error. Effectively, Wikipedia articles are the most peer-reviewed in the world. I trust them and donate regularly. NIGEL GUEST, Berkeley, Calif., posted on nytimes.com It is pleasant to think that selfless volunteer editors are working to arrive at unbiased answers on Wikipedia that everyone agrees on, but that's not the case. Those willing to spend more time and be more aggressive about their changes often win. And we don't know who they are. A person could be "guarding" a page that he has a personal stake in. It's all well and good to study suicide. But in discussing why doctors, including psychologists, are not able to predict who will attempt suicide, the article states, "Their patients often lie about their feelings to avoid hospitalization." Sadly, I've seen more than one suicide that may not have happened if the alternative was something other than hospitalization. We need mental-health urgent-care centers. They won't prevent all suicides. Nothing will. But they will at least offer a ready, humane and, for many, welcome alternative. Suicide can be but is not necessarily irrational, and it's a mistake to think that it always indicates some psychological disorder. The most obvious case in which suicide can be a rational (though not morally compulsory) choice is when a person suffers a painful, debilitating and incurable illness. Other cases are debatable, like elderly people who are alone and infirm, with no support network and few resources, who decide that they've had enough. It is tragic when people come to think that suicide is their least-bad option, but it's a mistake to medicalize all such decisions. Some are more rational than others. N. S. PALMER, Indianapolis, posted on nytimes.com As someone who attempted suicide herself, I think the constant focus put on pain by psychologists and those in the medical community often misses the mark. Pain for me and for many others is the step before. Complete inability to feel anything or to connect with anyone was the point where suicide became more of a reality for me. I was a ghost in my body, not really there anyway, and felt as if I was a burden on my family and would never get better. Luckily, I did not have access to a gun, and my attempts were not successful. Doing really well today and have been doing well for years. There are ways out of that level of depression - it is just unique for each person. JULIE K. HERSH, Dallas, posted on nytimes.com If Privateer Holdings" initial partners don't even want to be named, I would imagine that the next stages of venture funding, the series B and C rounds, will be tough. Even if Privateer stays "far from the leaf," they may still be too close for institutional rounds that are largely backed by pension funds and insurance companies. TOM HYLAND, Bangalore, India, posted on nytimes.com As an addiction expert who has seen the devastating effect of marijuana abuse and dependence, I can tell you that minimizing the risks of marijuana is the same tactic big tobacco used decades ago. In my private practice, teenagers who flunk out of college the first semester of freshman year often do so due to marijuana dependence. There is so much money to be made by future pot "businesses," yet for every dollar raised in taxes in the alcohol industry, we spend $10 in social costs.
