It seems once again google is updating add features. I just noticed yesterday new ajax based scrolling ads are coming up. This is a nice feature for people who want to see more ads for that keyword, but since no one likes ads I think this feature will come in handy in disguising your ads. It will look more like a ticker, or sliding content, so thumbs up on this one. Only thing not is that they come up once in a while so only some of your visitors will see them, but still it`s a nice feature.
