I would say that it must be judged on a site by site basis. I make changes on certain sites and watch the ranks change within days and have not experienced any drops for the changes. Yet I do make my choices and changes wisely.

I would think that you are probably tipping off the over-optimization flags as the previous posted said.

My advice, when you make changes, make them s-l-o-w-l-y and track to see what actually helps, and what hurts.
