Noam Cohen (February 9, 2014). "Wikipedia vs. the Small Screen". The New York Times. Retrieved 10 February 2014. One frequent mobile contributor, Sajjad Altaf, an information technology consultant in Findlay, Ohio, says he edits wherever it is more convenient for him, noting that "it is difficult to edit from the phone, but I guess not that difficult to deter me from doing it." Mr. Altaf has written entire Wikipedia articles on his phone, including one about Noor Pur Baghan, his hometown in Pakistan, and disputes the idea that smartphones are passive devices. "If you are using your phone, you cannot just listen but not talk," he said. "You cannot just receive an email but not reply to it."
