_Sorry, this is no answer, as the question includes no question `;)`_

I try to avoid anti-aliased fonts wherever possible as I second the opinion, that these ["hurt eyes and damage eyesight"][1].

The disadvantage is that a lot of web pages look ugly, because fonts are nowadays designed to be displayed anti-aliased only. Unfortunately this now also applies to SU (and the other StackExchange sites):

![enter image description here][2]

For sites I'm using on a regular basis I employ a user css to work around these font issues. For the SU site this works only partial... the reason is reveled by a look into SU's `all.css`:

    font-family:'Helvetica Neue',Helvetica,Arial,sans-serif !important

This `!important` statement renders my attempts with a custom css useless. 

Ironically, a [gold-badge answer on SO][3] clearly states:

> Yes, __`!important` is bad practice__. `!important` was initially designed to help people with visual impairments overwrite the style sheets of websites.

So finally I'd like to ask _why are in total 164 (as of now) `!important` statements used in the new style sheet_? Shouldn't the StackExchange sites serve as a shining example?
