BTW, it might help to have a title="digg" attribute (and similar for the others), as well as making the mouse pointer change to a hand on mouseover. It wasn't totally obvious to me which link was for digg (OK, you caught me, I'm not actually a complete nerd), and it wasn't obvious that the pictures were links, either, because the pointer did not change.
LOL
Okay, I nerd proofed it ;^)
I used the alt on the images for accessibility, and never thought to add teh title. There was no pointer because the links are generated with script, so I styled the cursor. See if it is easier now.
I want to encourage user to click those so that fix was important. We encourage all users to spread the word even nerds. hehe
