I find dictionary.com to be a very handy resource. But boy are their ads annoying. And it looks like they’ve gone that extra mile to get their popup ads to dodge around Firefox and IE+Google Toolbar’s popup defences. (At least I assume it’s them, not some other site with popups sitting in the background).
