Unnecessary content values
By default, Googlebot will index a page and follow links to it. So there's no need to tag pages with content values of INDEX or FOLLOW.
I'd be interested to read about negative effects observed from using INDEX or FOLLOW. I probably have all of my pages tagged unnecessarily with 'INDEX,FOLLOW', so will start removing those to see if I can correlate any effect to it.
