A pair of columns questioning a woman's very public battle with Stage IV breast cancer are lighting up the Internet. Former New York Times executive editor Bill Keller and his wife, writer Emma Gilbey Keller, both wrote pieces on Lisa Bonchek Adams, who is chronicling her fight via Twitter and her blog. Emma Keller's column (with a headline that compared Bonchek Adams' social media postings to "funeral selfies"), posted last week, was removed from The Guardian's website yesterday amid all the furor; Bill Keller's column was published in the Times yesterday. Both Kellers weigh various questions that seem to come down to this: Is Bonchek Adams engaging in "TMI"? And would it be better for someone like her to opt for a peaceful, quiet death instead of "heroic measures"? More. [BJS]
