Try Readability, an arc90 experiment. Just choose your format style, the font size and margin spacing, combine them in a customized "bookmarklet" and add to your browser toolbar and you can see the content clean and enlarged the way you like it. You can even email the article to someone in your format style. There is a video on the home page which shows you how to install the bookmarklet.
Check it out!
All the best,
Lon
