The title is deceptive, it would be more accurate to say SMS is on the decline. There is no evidence or suggestion that the behavior of sending short messages (typically via your phone) is on the decline, it just seems to be moving to proprietary protocols such as iMessage. Usually when I "text" I am actually sending an iMessage because most of my friends use iOS devices. It may be interesting to someone concerned about the SMS protocol that it is on the decline, but as someone interested in how people use devices this does not effect me.
