Pope Benedict and the Vatican just joined YouTube:
I added the Vatican to my friends list... we'll see if the Vatican responds! Today there were multiple releases from the Vatican concerning use of the 'new media' in evangelization. It seems to me the Church, as always, is slow to adopt new technologies, but slow for good reason—she always chooses the best!
YouTube's not the best medium because they offer the greatest quality or best services—far from it! But they do offer great community features, and one of the best ways of getting your multimedia content 'out there' on the web. We shall see if the Vatican uses the new channel to good effect!
(Here's my YouTube channel).
[UPDATE: Here's another article I wrote about this, over on the Office of Youth Ministry's website.]
