A Mini Hamburger Is Not a Slider

I have a couple pet peeves.
Scratch that.
I have a lot of them. And the New York Times just poked at one. Previewing tomorrow's food section coverage, the Diner's Journal blog foreshadows some "slider" coverage:
Meanwhile, back in the home of the burger, its most humble version, the slider, has been getting a makeover. Florence Fabricant writes about how it’s become trendy, high-end bar food, as likely to be made with seafood, chicken or cheese as with beef.
I'm guessing this is going to be another one of those "slider" roundups we see every few months in various guises and in sundry publications. My ire is piqued here by the notion that sliders can be made with seafood, chicken, or cheese.
They can't.
