At what point does your ad become over exposed? I don't know if it's the same ad or not, but over the last few monts I keep running into a pop up for a video cam, that has become extremely annoying to me. I see that it's now on geocities in addition to the small popup that they already have. I'm sick of seeing this ad, especially since on geocities it open up a new window on every page. There is just no way that I'm going to buy this product because the ad has annoyed me too much.
