Jacob Neilson’s site about the top mistakes. (Alertbox) I’d add one more rule: Making a site really ugly. But mever mind he is right about the ones that he has there, and I stick to them here, but for one:
“8. Non-Standard Link Colors
Links to pages that have not been seen by the user are blue; links to previously seen pages are purple or red. Don’t mess with these colors since the ability to understand what links have been followed is one of the few navigational aides that is standard in most web browsers. Consistency is key to teaching users what the link colors mean.
I think the way that my site is layed out leads one to know what to do… hope so.
