@ericam I don't find the current clearfix mixin to be useful at all.  The time it takes me to type out `overflow: hidden` is the same as the time it takes to type out `@include clearfix`  I *do* use both methods of clearing floats, but when I invoke a clearfix mixin, I want it to be one that uses pseudo elements.  Otherwise, I can just type it out like a big girl..  A mixin that only emits a single line that isn't configurable in any way feels wrong to me.

Messing with overflow is not an appropriate choice for clearing floats when you have content that you *want* to overflow (eg. drop menus).  A pseudo element clearfix is the better choice for an all-round solution.
