We've updated our browse pages today and one new change we'd love your
feedback on is the ability to view more thumbs when you hover over a
video.

http://www.youtube.com/browse

When you mouse over the thumbnail, you will see a few representative
images auto-scroll for that video. We're still working on optimizing
the look & feel, and looking into expanding this for other pages on
the site.

Please share your thoughts with us in the following discussion thread:

Thanks!
