Regardless of whether or not anyone here would buy a magazine because Kate is on the cover, obviously there are a lot of people who would, and do. Magazine editors don't put people who don't sell on the cover of their magazines. They put pictures of people who will sell well. Editors have one goal ... sell magazines, sell newspapers, as many as they can. Because if they don't, they get replaced. It's that simple. When she stops selling more magazines with her picture on the cover than without, then they'll put someone else there. There's also a discussion about this somewhere on the forum, and there's also a discussion somewhere here about how many covers Kate was on last year. I don't have time to look for them right now. Maybe tomorrow.
I'm not surprised she's not as popular as Diana. She probably never will be. She's an entirely separate human being, she's not trying to be Diana, so why compare her?
