Were these Winter Olympics the best ever?
Early in these Winter Olympics a furore was caused by a journalist asking if these Games were turning out to be the worst Winter Olympics ever.
Now I'm ready to pose another question, which will probably provoke just as much debate. Have these actually been the best Winter Olympics ever?
Let me clarify that question a little. In many ways there are always two parallel Olympics which take place - the one that viewers around the world watch on TV, and the one that spectators come to a city to enjoy in person.
For example, the Beijing Olympics were considered to be a great success by the international television audience, whereas many people who witnessed the Games at first hand complained about the lack of atmosphere in the Chinese capital.
I was in Beijing, and I can assure you that you simply cannot compare the spectator experience there with the one here in Vancouver. Vancouver wins hands down.
In Beijing there was little buzz around the city. Yes, they were a fantastic Games in terms of quality of venues and competition, but not in terms of the amount of fun that people were having. Here the street party began on the opening night and it shows no signs of coming to an end just yet.
One senior official from London 2012, who's been in Vancouver, told me that she's learned more from five days in Canada than she had from three weeks in China. That's because, in terms of spectator experience, London will be looking to follow the Vancouver model.
I haven't seen much of the TV coverage, so it's hard for me to judge what your personal opinions of these Olympics will be, but I hope that many of you will write your views here.
In the meantime I'll focus on my experience of the Games, having now spent nearly three weeks in Vancouver and Whistler. So, I should probably refine my opening question just a little: Are these Winter Olympics, in terms of spectator experience, the best ever?
On Friday I was outside the Broadcast Centre grabbing some fresh air when I saw a large crowd heading down the street towards me. At the centre of the throng was a big Canadian flag being waved proudly in the air. As the people moved closer I could see that the man carrying that flag was Jon Montgomery, a Canadian gold medallist last weekend in the skeleton.
Around him, an impromptu procession had formed - a celebration of home-grown success. The further down the road that Montgomery went, the more people tagged on behind. If this had been a scene in some other countries maybe there would have been accusations of over-hyped nationalism, but this felt spontaneous, natural and very good natured.
I had witnessed just one of hundreds of events that have been taking place on the streets here every day, but for me it summed up one of the successes of these Games.
When I interviewed John Furlong, the chief executive of the Vancouver Olympics, last week, he said that he wanted the Games to help unite Canadians. Few would argue that hasn't happened over the past two weeks.
These have not, though, just been a Games for Canadians, they've been an all-embracing Games. The Canadian people could not have been more welcoming. All the athletes I've spoken to have said exactly the same.
Foreigners have been welcomed with open arms. It's almost impossible to travel on public transport here without a local coming over to speak to you (admittedly the BBC accreditation around my neck is a bit of a giveaway) and ask how you're enjoying the Olympics. There's a real pride here in Vancouver, as we saw from the strong response to the original articles which were so critical of the Games.
It's going to be interesting in London in 2012 to see if the British people get behind their Olympic team in quite the same way as the Canadians have here. Flags fly in every shop window, and are displayed on hundreds of thousands of shirts and jackets.
My producer, Jon, noticed early in the Olympics that a number of people were wearing red Canadian mittens. He decided that he'd buy a pair to take home for his wife. Two weeks later he's still looking! Every shop has sold out. They've become the must-have fashion accessory of the Games - millions have been bought.
It's just another illustration of how Canadians have united behind their country's flag. Even Oprah Winfrey was excited to be able to give some away on her show the other day.
I can only write about my personal experience in Vancouver, and, as you can see, I have little but praise for the way that this city has handled the Olympics. These are only my second Winter Olympics, so I'm in no position to say that they're the best ever, but in terms of spectator experience they definitely compare favourably with Turin four years ago.
And how about this for a compliment from a man who really should know what he's talking about? The IOC president Jacques Rogge told me in an interview (which you can watch here) that the people of Vancouver had "embraced the Olympic Games like no other city in the world before".
Many other seasoned Winter Olympic observers are also putting Vancouver right at the top of their list. Are they at the top of yours?
