If we remember back to the discussions here in the years pre-Panda, we saw something like the following very very frequently:
"I made a minor change to a couple of my pages and then I dropped in the SERPs."
It got so crazy that people like me were hesitant to change anything for fear of losing position. This was especially true at those sites that were getting a good rank. We heard "if it ain't broke, don't fix it" and "best to leave well enough alone", and because of the ongoing testimony from many professionals regarding a correlation between site edits & subsequent position drop, that advice had merit.
So from POV, nothing has changed ~ we STILL don't know what to do with any degree of confidence and no degree of certainty.
I like what potentialgeek wrote ~ that is a conservative approach that makes sense, and if thereafter you do get bitten by the Panda, you'll at least feel you made your best effort to protect yourself. Otherwise, nothing will change on our sites, which cannot be good for user satisfaction.
So pick your poison....
