From a New York Times Insider column by Susan Dominus headlined “A Reporter Who Puts Herself Into Perspective”:

When I speak to journalism students, I usually advise them to use the first person point of view in their reported works with caution. Writing in the first person can make for facile transitions (“I met her at a crowded restaurant”) or reveal reporters’ mistaken impressions of their own significance to a story. It can set up the expectation of more personal insights to come that are never realized; often, it simply feels extraneous or clumsy.
