Esoos reports on a HighRanking thread named Yahoo And Nofollow, They Follow?? The thread basically shows how Yahoo! is accounting for backlinks that are using the nofollow tag.
I am pretty sure that Yahoo! (Tim Mayer) said at a conference that if a nofollow tag is used, the spider will simply not recognize it. Folks in the forum tend to think that Tim meant they would not "trust" the link. But I am 99% sure they said they would not follow the link, as if it wasn't there.
So what is up? :)
