I may be strange and unusual, but I just have never cared about my Google ranking. I know this makes me out of the ordinary among site owners but I have been humming along fine.
This certainly will disrupt traffic but for some of my sites I honestly think this is a good thing. I want you to want to be there, not just stumble upon my site because you happen to hit the right search keyword. Plus if it gets bad, this does create a new opportunity for others with cross linking and search.
