1) I hate googlebombing
2) I do some dev work myself and think I understand how your site is built; i.e. I believe the footer is an included template and thus it stays on the main page and on all the rendered pages forever (or until you take it off) and thus becomes another end-around to the Google ranking system (as I understand it Google gives less weight to links that fall off the main page).
And (this is the important one)
3) I didn't think. I read something in a hurry, thought I had stumbled across one of my hotbutton issues, and completely blew my stack.
