On Sunday, Subway Reads started delivering novellas, short stories or excerpts from full-length books to passengers’ cellphones or tablets. The idea is for riders to download a short story or a chapter and read it on the train. Subway Reads will even let riders choose what to read based on how long they will be on the subway — a 10-page selection for a 10-minute ride, a 20-page selection for a 20-minute excursion, a 30-page selection for a 30-minute trip. Delays not included.
… Subway Reads will last longer than a summer romance, but not much longer. It was intended to promote something that will not disappear, something that transit officials see as a milestone in the digital age: Wi-Fi service in 175 underground stations.
