So His Holiness Pope Benedict XVI has signed up for Twitter. Having settled on the snappy handle of @pontifex, the Vatican advised followers to note that tweets shouldn't be regarded as "infallible teachings". But they won't be Instagrammed LOLcats either - the Pope will use the account for live responses to questions about faith during his weekly general audience, starting December 12th.
The Pope joins the Dalai Lama (5.6 million followers) to beef up Twitter's regiment of religious leaders who engage with believers on the site.
What do you make of the Vatican's decision: is it a wise move for the 85-year-old Pope to jump on board? Have your say in our poll below.
