I'm of the experience that adding nofollow tags to a few sites I recently revamped helped serps.

I can't conclusively suggest that it was indeed the nofollow tags that were responsible--it could have very well been a number of other factors including cleaned up html source and the like. However, the nofollow tags were the only new item I added and hence the cause and effect in my mind.

Just my two cents.
