Instagram has been around for what, maybe a couple of years? Already it has shut down some small blogs - it's a collector of others and those most followed. It's already a selection. I imagine this further selection will take place in the next two years. It's going to be very fast.

I think very highly of Expo and all is going well. We've seen big problems with [corruption] scandals [at local government level], but it is going forward, with the highest number of participants ever expected.

This is a choice I made 26 years ago when I joined the magazine. Vogue was in Italian but I wanted to speak to everyone so I thought of creating images that were made to talk.

There are designers there, we have to think of production, but I am not changing Africa. But if we all do something together....We have to know our limits, I don't have the pretense I can change the world. And I don't want to set up events [to raise money]. Because what happens if the following year they don't have an event, they won't eat?

The only time I was really surprised was the reaction to the [shoot dedicated to the] BP oil [spill in 2010]. I didn't expect it at all. It was for the August issue, perhaps one of the less relevant months, but there was so much buzz. It was picked up all over the American television, but I defended my position. I don't understand those that say that a magazine such as Vogue should not talk about these things.

I am very favorable to the Bourse, to a sale, to what is useful to grow, maintaining jobs, the Made in Italy. It doesn't make any sense and it's parochial to think otherwise. Investors can be French, Russian, as long as they help a business grow.

You can get tired of anything, everything turns old, but I want to give people the possibility to share a Vogue party. It is up to the brands to participate to make the event interesting. I am satisfied, but it's important never to stop.
