@ Eric – my text looks like a regular Helvetic/Helios/Ariel style type face in the a letter O forms a perfect circle and is not given the illusion of height by reducing the character width.
Perhaps your browser has preferrences that have been set to change the displayed text because I cannot see any large, tall (compressed) or overtly pixelly headlines unless I sit close to the screen. Change the zoom settings in the bottom right of your page is probably easy enough to resolve the issue.
