>> the ad in between page loading feature
Weather.com has then on every load it seems. Strangely, I don't find them that annoying on desktop. In some ways less than on-page ads that clog up the page load. Of course that's because Weather.com has trained me to wait for ad, close it, then get my forecast.
It's been a long time since I've had AdSense on anything, but it appears to be one of the few subforums at WMW that still seems to get new topics.
