It looks like yahoo is going back to stone ages...... Look at the results in their index.... guys are doing black hat thru .edu domains redirecting users to own pages... a lot of mambo search crap appears in financial keywords as well....... and this come up I think in their new index...
well, I will not publish exact url because many of you start using the same technique, but I see that yahoo new algorithm gives more weight to .edu sites and yahoo slurp is unable to detect cloaking / redirection....
