New York Times public editor Margaret Sullivan addresses concerns raised the paper's decision to use geo-location data to "personalize" online stories. "A New York Times that gives readers too much personalization could become more of an echo chamber than a news provider," she writes. "As the paper continues down this path, it’s important to do so with awareness and caution. For one thing, some readers won’t like any personalization and will regard it as intrusive. For another, personalization could deprive readers of a shared, and expertly curated, news experience, which is what many come to The Times for."
