One of the virtues of YouTube is that you can get a sense for how a speech went down by inspecting the unsolicited comments that viewers have added.
Here are the first 10 (of 208) listed at the time I looked at this particular clip of Prince Charles' speech at his mother's Diamond Jubilee - and I don't think I've ever seen so many consecutive positive comments about a speech on YouTube:
"Charles - that was a class speech. Witty, humorous, thoughtful and loving. Good man."
"What I love most about this video is that we get to see the Queen show some emotion which unfortunately we don't get to see very often because she's the Queen. Proud to be British and proud to say we have her as our Queen!"
"King like speech so proud to be british well done charles"
"Never got the animosity to Charles. Glad to see he's turning the tide."
"He will make a great King!"
"makes you jolly proud to be british!"
"This was a really great speech. Witty, thoughtful, and charming."
"What a great weekend, and an equally superb speech from Charles, the best I have ever heard him give, hats off to you sir! I pray this will light the blue touch paper and we can find it in our hearts to start talking the country back up again."
Sullen celebs in the background?
I've written and blogged before about the dangers of allowing other members of an audience to be seen behind the speaker who's speaking.
Here, the Prince of Wales might think about awarding his stage managers the order of the boot - because the first negative, and, in my opinion totally reasonable, question on YouTube was "Why do Elton John and Paul McCartney look so grumpy?"
