Content
should take up 50%-80% of the web design real-estate

You have 10 seconds
while downloading to keep the
users focused attention
Top site average 8 seconds
to display as compared to the
WWW mean of 19 seconds

Pages that are <33 Kb have 7-10% of users leave the site before it
completes downloading

Pages that are >40 Kb have a 25-30%
bail out.
Web vs. Print
When reading a magazine the user must expend a lot of energy to change to a different magazine...
...on the Web, change is a click away, making the user less likely to stick with any site that doesn't keep their attention.
Your site should be tested by someone who is Red - Green colorblind
