Conde Nast recently announced that Mademoiselle magazine is folding after being around since 1935. Besides the problems with the format being revamped several times, they've also cited the events of September 11 (and their economic fallout) as part of the reason.

Even though I haven't read Mademoiselle for years (because after I turned 30 or so, I felt like the magazine was kicking me out), I am still somewhat bummed to see it go. It was the first "grown-up" magazine I ever bought.
