There's a wonderful story in New York magazine where the writer, Emily Nussbaum, remembers why she fell for Madonna in the first place, tries to determine when she fell out of love with her, and then tries to learn to care again. It's not a profile, and it doesn't pretend to be. Instead, it's one of the strangest love letters you'll ever read.
I love this line: "For years, Madonna felt like a slippery, elegant key to all feminine mythologies, a shape-shifter inspiring to any young girl (or anyone) who felt her shape shifting."
They've also got a slideshow of 75 great Madonna magazine covers. It's like there are 75 different people up there. No wonder magazine editors love her so: it's pretty soul-destroying having to put the same old face on your cover every year.
