According to the CSS it's '"Lucida Grande", "Lucida Sans Unicode", helvetica,clean,sans-serif;', so this might be a browser/setting kerfuffle. It works fine for me (FF/Chrome/IE on Win7).

If you are "so done" you can choose not to read it. Or you could change the fonts by hand. Or you could use some addon (like Readability or Evernote Clearly) to make it better. There are many options available to make you enjoy the content wich is really what matters. Aren't you a hacker?

I feel the same thing about HTML5 with dynamic everything and pointless whitespace and extra borders. Completely unnecessary. To each, their own.
