Nieman Lab: That unique confluence of New York Times readers, pope watchers, and WhatsApp users must have been excited when the Times announced it would be experimenting with the messaging app to deliver updates on Pope Francis’ visits to Ecuador, Bolivia and Paraguay. The tour began Sunday when the Pope landed in Ecuador and will last for nine days, during which time the Times will be sending updates via WhatsApp to those who signed up.
