Is Palestinian Arab unrest in Jerusalem the sign of a third Intifada, or uprising? The Times' answer to this question apparently depends on what time of day you look at the paper's website. The useful site NewsDiffs.org tracks how, over the course of the day, the Times changed the headline over pretty much the same news article, from "Few See New Palestinian Intifada in Jerusalem Unrest" to "In Jerusalem Unrest, Signs of a 'Run-Over Intifada' for the 21st Century." It would be nice for the many readers who saw the first headline on the Times home page during the day to get some notification or explanation of why it was changed. Did it become inaccurate?
