I haven't noticed much of a change. The ads are so obnoxious on this site that it overwhelms any other changes that might be made. Even as I was reading through this thread over 50% of my screen was taken up by ads. That is an unreasonable amount of ad space IMO.
If I listen to a 3 minute song on Youtube, I might have to hear a 5-30 second ad first. If I were to apply the proportions used by this site, then it would be more like a 4-5 minute ad to hear a 3 minute song. I understand ads are necessary, but at a certain point it becomes too much.
