I have turned on Windows like smoothing (according to http://webkit.org/blog/168/gdi-text-on-windows/ ) in last nightly WebKit-r31238 in Windows XP. It works correctly on many pages but on http://twitter.com/hassmanm it doesn't use Windows settings. Looks like it uses classical WebKit smoothins on this page for some reason.

WebKit always uses Core Graphics rendering for the Lucida Grande font family.
