Here I do some live tests on both Google and Yahoo to see the difference, and see the interesting information we can retrieve by utilizing the NoFollow adaptation.

Yahoo and Microsoft both supported the tag at the time is was launched: http://googleblog.blogspot.com/2005/01/preventing-comment-spam.html
Funny they thank them. However this post clearly shows Yahoo at least does not apply it:

Yahoo have clear stated (when asked by SEJ) that they still follow for discovery but don't attribute juice.
I actually find Google and Yahoo results fairly similar, though Yahoo tend to place more weight on URL / Title and there are less problems with supplemental results.
Rel="nofollow" never meant "do not follow this link to its destination". Google has changed that behavior a long time after the standardization, it's relatively new that Googlebot does no longer follow nofollow'ed links.
rel-nofollow is defined as "do-not-pass-reputation", so it's within the standard when Yahoo follows these links, indexes the destination, but doesn't weight the link.

The fact that so many folks do not understand the rel-nofollow semantics makes it evil crap.

Sebastian, you are very wise...
