I really wish there was a way to exclude certain videos from their feed recommendation engine. Or at least put them in a different category. If someone sends me a particularly funny cat video, because it is their cat, I really don't want to get a deluge of cat videos. Also, if you are playing videos for your 2-year-old, those shouldn't influence the playlists that come up when you are driving to work (the Gummy Bears videos keep popping up in my 80's playlists).
