Panda is different from the perspective of how it was integrated into their algorithm.
Historically Google updates their algorithm and changes can be tested against that almost immediately.
Panda has essentially taken that testing out of the equation by applying the algorithm change, pulling out the sites that get picked up by the algorithm. You can't test your way out of it until they decide to re-analyze your site. Which appears to be few and far between and randomized... Hence we have a ton of webmasters running around upset that we can't figure out what is wrong with our sites.
So yes, there have been folks hit far worse by past updates, but this new technique they are using is a first... and is very effective for what they are trying to accomplish. It is just very frustrating for those false positive hits that get sucked into it and stuck for potentially eternity.
