I forgot about it even being there since I run into them on other sites as well at times but never bother clicking on them. It would be less confusing for anyone not familiar with them. Can I second the notion?
One other idea for keeping them would be some type of indicator or script to show them. If you go to an MS page you see a "show all" link under each catagory on a questions page. On some sites however you have to move the cursor around endlessly just to find the right spot to click on.
