The website is most probably designed in Mac and the designer forgot that Lucida Sans and Lucida Grande do not exist in Windows by default. Although the Arial and Verdana are also declared in the CSS, however for some weird buggy reason, Windows fails to perfectly render the text in either Arial or Verdana, or any other sans-serif font. That's why it looks like sh*t.
In my Linux, the text seems okay and perfect although my computer lacks any Lucida typefaces.
