I’ve been doing a lot of playing around with ajax now and last night I saw something that took my breath away. I should have known it was coming, but sometimes you just hope for the best. A site had taken to using ajax style elements to produce popup ads within the page. It floated over the middle of the page and wouldn’t go away until you clicked on it. It was annoying as hell, and I won’t be going back to that site again, but this is an ad networks dream. It’ll get around pop-up blockers. You can’t just ignore the ad, you have to deal with it. It’s in your face and going to be very difficult to screen away. Really a bottom of the barrel technique, but it seems that there are plenty of people out there willing to use these techniques. This is going to bring a whole new level to thinking about dynamic web pages.
