This helped make reading this a little easier. Copy and paste to your URL bar. You may have to retype the javascript: as it appears to get stripped for security.

  javascript:$('.entry').css({ "background":"#fff","color":"#333","padding":"10px","font-family":"Arial, 'Helvetica Neue', Helvetica, sans-serif","font-size":"14px","font-style":"normal","font-variant":"normal","font-weight":"400","line-height":"20px" })

You can also just turn styles off ("View > Page Style > No Style" in Firefox).

Or even better, if you`re in a recent version of Firefox you can click on the little "open book" icon in the address bar and enter the reader mode which looks pretty nice as can be seen in http://i.imgur.com/oiZGekO.png
