Magazines aim to be timely and smart, not wise or profound. They have the planned obsolescence that Tocqueville observed in American architecture. A new issue comes out next month. You are supposed to throw the old one away, and most people do. This is natural, and maybe tautological.
Magazines have to make money steadily.
Consider, by way of contrast, writers of books. Merely individuals, they can sink costs almost indefinitely. If they want to write in styles ahead of or beyond the popular taste, they are free to ruin their own and their families' finances and their books may still see print. But magazine editors don't have that luxury. If they stop paying their bills, the magazines die.
