I like it on the right instead of infesting the main. It's logical, too. The eye is trained to look at the right side for extra links (advertising links). Like I said before, Google needs to customize search results. Let us decide, based on Preferences, how many extra links we want, and what kind. News/Media/whatever.
For example, your Preferences could say:
Video
[ ] High
[ ] Medium
[ ] Low
[ ] None
News
[ ] High
[ ] Medium
[ ] Low
[ ] None
If you check Video High, you get 6-10 youtube/video results with your text results, in the right column, or on the right side.
If you're a News junkie, and you check High, you get 6-10 headlines.
Very basic. There's absolutely no reason to clutter our results with junk we don't want and won't use.
BTW, it really isn't a clean interface when they throw in the Video clips in some random part of the left column results.
I think the News results, maybe Video, too, could go underneath the Sponsored Links on the right. I suspect it would lead to more clicks on the ads, as many people will start reading at the top of the column, and read the ads before they get to the News/Video links... More money for Google.
