Social Media and Purgatory

I must confess I didn't see this coming:

The Vatican has taken another step in its efforts to embrace social media by offering “indulgences” to followers of Pope Francis' (@Pontifex) Twitter account. Italian newspaper Corriere della Sera reports that the church will reduce the time Catholics have to spend in purgatory if they follow official Vatican events on TV, radio, and through social media.

Can't you just imagine @DrMLuther nailing an iPhone with the #95Thesis displayed onto the door of the Wittenberg cybercafe? Charles V would have had a much easier time if he could have just tracked trending hashtags.
