I've just checked the backlinks of a competing article on a article directory with yahoo site explorer. Now here is the funny part. According to it, my competitor has a link from one of my sites that points to HIS article, not mine. There is no way that there was a link to his article from my other site/domain EVER. What the hell is going on? Is yahoo site explorer not reliable anymore? I just rechecked, it still points to my article directly... wtf?
