I’m not a big fan of the default text rendering in WebKit, in my opinion, it’s too heavy. There used to be a workaround where setting text-shadow would make the text thinner, but updating to Snow Leopard rendered that useless. Then someone found another hack using -webkit-text-stroke that seemed to work nicely, but it wasn’t usable on text-heavy pages, causing performance issues when scrolling. So you can imagine how happy I was when I saw Faruk Ateş tweeting something about -webkit-font-smoothing. Being the CSS geek I am, I whipped up a demo page you need the latest WebKit Nightly to properly see that page to see what exactly it did…
