Call Centers are not particularly effective. It's also true that there aren't widely available good options.
It's a difficult situation, and the tools to address it are inadequate.
Maybe not a great thing to do on a high-traffic website on the day of a high-profile suicide.
It's the only time people seem willing to discuss suicide. A week from now everyone will have forgotten that suicide is a real epidemic. I'd rather see people discuss real solutions instead be of endlessly repeating the same pointless things.
Has self-directed CBT actually been studied?
As far as I understand most people receiving CBT who have been studied have received it in a professional setting with weekly meetings.
Then yes, there was actually a study of the book Feeling Good (kind of meta), and told to read it with a checkup every 6 weeks just like you guessed it in the quote. There are other CBT books that are smaller and to the point, more tactical approach to learning the methods (I think one is called Learning CBT) of Feeling Good. The second half of Feeling Good goes into drugs, which at the time was written no long term studies had been done or possible. From my personal research, these drugs do not work and cause more damage then good. I have found that through suffering and depression, and then working my way out of it, I believe I am better off then just taking a drug. I feel they are supressing some kind of natural force that is needed to build character, but for some people they are needed as a "backstop" to get out of a hole. On another note, depression has grown several folds since the introduction of antidepressants. I do not even consider that there is actually a thing as a drug that can do what they claim, but that's my personal belief.
