I was pretty interested earlier to come across The Royal Channel, the Official Channel of the British Monarchy on YouTube. At first I suspected a joke, but there is a link from the official 'royal' site. Somebody seems to be putting quite a bit of thought into the Monarch's web presence.
The 2007 Christmas Broadcast had already been viewed over 820,000 times.
(I came across this as I am writing an entry on Alan Bennett's quick read The Uncommon Reader, a fictional account of the awakening of the Queen's sensibilities through a late interest in reading.)
