What exactly is a "trick" then? I would argue that they're useful bits of functionality that a group of people might not know. For instance, if I post "math tips and tricks" to my facebook followers they'd be like "ooh, nice tips" but if I post them on a /r/mathematics I'd be told "they aren't tricks, that's just the way math works". I think you're just basically saying "I know this already so everyone else should too".
