GetContentSize is a cool utility that will tell you the percentage of a webpage that is text and the percentage that is markup. Info for this page:

Total page size: 40882 bytes (not including images, attached scripts or style sheets)
Text content: 10811 bytes
Text content percentage: 26.44 %

That means 73.66% of my page isn't text and thats not good. I think I might edit this program to also count the percentage that is urls because they provide vital information to a page. Maybe that will give a better representation of what's important and what's garbage
