I spend less time on your site than you think. Be clear and precise. Use headings and boldface to orient me. Don't use ambiguous links. A link is only useful to me if I know where it will take me.
Broken links suck.
Clean up after yourself. Do some housecleaning. Surf your own site and get a clue. Eat your own dog food. I'll immediately leave your site if any link on the home page doesn't work right.
