The quality scoring assigned by Panda seems to be extremely sticky and for now, at least, almost impossible to change in a dramatic way. Panda is not acting like a traditional "penalty" at all, and it may be a mistake to think of it in those terms.
But the return of traffic to those who did some changes and succeeded -- they seemed like a penalty was lifted? It seems very binary.
Also, I'm seeing the same things as with all of you making drastic changes. The changes are, in my mind, for the better, but at the same time, saw a 10% to 20% drop right after any crawls. Very odd indeed! If I keep at it, I'll have ZERO google visits, and by that point, I won't have anything to lose... (snark).
