On another point, I think the allusion to the suicide being timed for media exposure unlikely to be true, despite how media savvy Ms Dawson was. Suicide is often unplanned and responding to an overwhelming sense of despair that is hard to overcome or delay. That she was having to leave her home, her sanctuary as the author says, so it could be opened up for an open home for it to be sold, was more likely the trigger for the timing, as well as her housemate being away. People who suicide find it very hard to look into the future, to see that life can be any different, and I doubt she would have been thinking about newspaper sales as a factor in when to end it all (and it was overshadowed by the memorial of the earthquakes in NZ in any case).
I would really appreciate it if the author could remove the mention of the method of death please. Previous cases and suicide research (which I've reviewed for a suicide prevention guideline in NZ) suggests that some vulnerable people can have their own depression triggered by media portrayals of suicide and can use copycat methods. It has happened quite a few times in schools. Media are advised to not go into detail about methods in particular which is hopefully why it hasn't been covered elsewhere. Charlotte Dawson's struggles with depression were well known and she had many followers who may have been inspired by her fight against cyberbullying and who will have taken her suicide very badly. So one has to be very careful in the coverage.
For advice to media on reporting about suicide, including a suggestion that method not be detailed, and links to research that contributed to this advice, please see this page: http://www.health.govt.nz/publication/reporting-suicide-resource-media
(BTW, I have not seen the method mentioned in other media to date, fortunately.)
