I used to avoid About.com because of those horrible frames, now I can browse there.
But still, I don't like sites that force you to stay longer than needed.
Looks like an updated version of About.com Ad Free.
But it does not work on those links that show the direct URL but add the top frame after

eg. Try 'Visit the site' link at http://mp3.about.com/od/digitalmusicdelivery/fr...
