The Pope's Twitter Account Revisited

Back in December 2012, Pope Benedict XVI was the first pope to open a Twitter account.  See my original post on this here.

Pope Francis, not to be outdone, also created a Twitter account.  Take a look at it here;  scroll down and look at his last posts of the last few months.  What do you notice?  Why would Pope Francis take the time out of his busy schedule to maintain an active Twitter account?  Can you use our economic approach to religion to think meaningfully about the pope's Twitter usage?  Does the notion of religious capital provide any insight?

(OK, it is possible that one of the pope's assistants does the actual posting with some input from the pope, but let us just assume that the pope is actually choosing the content).
