The Magazine Rule

"There's a magazine for everything."

A character subscribes to a weirdly specific fandom magazine or trade publication you would never expect to have an audience, or that speaks volumes about his character. This either represents his interest in a very niche hobby, or shows that a perfectly ordinary part of life is Serious Business to him. If it's a trade publication, he probably belongs to a Weird Trade Union.

Named after The Wiki Rule, its online equivalent. Related to Collector of the Strange and Pastimes Prove Personality. If a Manly Man subscribes to Cross-stitch Quarterly, it's Real Men Wear Pink, and if a Nightmare Fetishist has managed to find a publication devoted to Cross-stitch Bondage Babes, it's Rule Thirty Six.

 * Parodied in Community with Dean Magazine, which at point plans to do a cover feature about Dean Pelton.

Double subverted in that the publication which informs us of the cancellation of Dean Magazine is none other than Magazine Monthly.
