"Saint-to-be tweets from beyond the grave" - is this for real?

My agnosticism and skepticism keep me from getting carried away with this, not to mention that I would need hard evidence just to try and become a believer, but nevertheless, it sounds interesting.
Reading the article (link here below), I loved this the most: Sister Arnold told AFP, said it was "absolutely critical" that the Roman Catholic Church embrace new methods of communication. Maybe soon enough we can see the Pope twittering and setting up a Facebook page. That would really increase his popularity among teens...
