Possibly because Google know it's not that good.

Yeah... I suppose, but they're (the intext networks) NOT Google.

It's got to be the most annoying advertising concept ever conceived.

Actually, I don't find it annoying when its use is controlled - meaning some webmasters go for bang and set their limit to "unlimited" which causes EVERY mouse roll to trigger a pop-up while others set it to "5".

I think if Google were to go for a minimalist approach - no fancy, schmancy animation, just a simple pop-up with Adlinks type of content within the pop up, it might do good.

Just a thought.
