These guys need to get over themselves. JQuery provided a really nice way for designers to copy/paste effects onto web elements. And then they took it way, way too far, to the point where whenever I see a "new JQuery plugin to do X" I just look the other way.
JQuery just gets in the way these days.
$("#element") is an anti-pattern. That code should just return the DOM node, not some silly object with unknown attributes. We're way past the point where you need to abstract the entire document object model, and I argue you should never have done that to begin with.
