Well I don`t think that VP would change their font just because of a tweet. And no matter how many times we wish for a new font, I don`t think they`ll change it. That font is customized for them and I doubt that it came cheap. So I think Emmanuelle would stick with it for quite some time.
At first I wasn't struck on the font change, although I'm coming accustom to it. One of the factors for me being obsessed with Vogue Paris, was actually their fonts and layouts. As soon as I get the issue I always rush to the page before the editorials, I love to see variation between layout and text placement ideas. Especially with issues from 2005-2006!
