I'm pretty sure I'm gonna get slammed on this.

I love using the data-whatever attribute to bind events to.

It feels very clean to me and helps reserve my class attribute for just styling.

I know this selector is among the slowest, so I don't use it when there are a lot of elements.

Would love to hear compelling arguments against this.

$("body").delegate("[data-action]", "click", function(){
var action = $(this).attr("data-action");

//route action to appropriate function

});
