Well, thanx to a comment, I installed adblock. It gave me errors at first, but installing as root pretty much fixed that.
I added http://images.slashdot.org/banner/* and told it to hide it. Much better. It's too bad though. For a while there I liked slashdot ads. They were clean, and unobtrusive. But, they stopped being so nice. Oh well.
On another note, I like Google's ads. Those are nice.
